Temperature is high on one side and low on the other
there is heat flowing through it from the middle
How can we extract the energy that is
This is an ideal thermos with hot water inside it
kept it for 100 years, millions of years, billions of years
The world has ended, it has been destroyed, come back new
I've gone and in the next life who knows how many centuries
Are you studying thermodynamics?
will there be any heat flow from there to here, any heat
If there is no flow then we will call that state
I wonder what happened here thermal
The way to go is called
A process is a state, which means there is a pressure on it.
don't flutter it is ok on this thing it is written D Every creature here is clear, every single one
Every creature here is clear, every single one The creatures are sorted, each creature has a thing
The creatures are sorted, each creature has a thing I understood it brother, okay, now let us first
I understood it brother, okay, now let us first Bhaiya, we will talk about the limitations of the law
Bhaiya, we will talk about the limitations of the law What Are the Limitations of the First Law of
What Are the Limitations of the First Law of First Law of Thermodynamics
First Law of Thermodynamics what is the limitation of thermodynamics ok
what is the limitation of thermodynamics ok so here is its limitation it does not tell
so here is its limitation it does not tell As about the direction of energy flow
As about the direction of energy flow Will just tell us how much heat came, this happened
Will just tell us how much heat came, this happened Its not about direction who is the heat
Its not about direction who is the heat The heat has come and gone, now finally it is too much
The heat has come and gone, now finally it is too much Where and who is getting energy from in detail
Where and who is getting energy from in detail Not going into so much detail
Not going into so much detail Sign takes wine, its a straight calculation
Sign takes wine, its a straight calculation So many had come, so many took so long to understand
So many had come, so many took so long to understand Who came and who gave to whom and who took the Rs.
Who came and who gave to whom and who took the Rs. It doesn't go into detail about what you took.
It doesn't go into detail about what you took. I am not able to give you much detail about this thing
I am not able to give you much detail about this thing does not tell us about anything weather the
does not tell us about anything weather the The process is spontaneous or not even this
The process is spontaneous or not even this I do not tell you what process you did for heat
I do not tell you what process you did for heat I have calculated it, I don't know if it will even happen
I have calculated it, I don't know if it will even happen You are not able to process it and you are heating it
You are not able to process it and you are heating it you are sitting there calculating so this one which
you are sitting there calculating so this one which The thing is this is also its limitation first
The thing is this is also its limitation first What is the Law of Thermodynamics Concerned With?
What is the Law of Thermodynamics Concerned With? Conservation of
Conservation of energy obviously okay the next one when the
energy obviously okay the next one when the heat is supplied to the system equal to
heat is supplied to the system equal to increase
increase in when is the heat supplied to the system
in when is the heat supplied to the system Equals to increase in its internal energy
Equals to increase in its internal energy Now, as many times as you think of the question, you will remember that of Papa.
Now, as many times as you think of the question, you will remember that of Papa. Look at the example and think that
Look at the example and think that Bhaiya papa gave you 0
Bhaiya papa gave you 0 isn't it, this is it q=y pd do you remember this
isn't it, this is it q=y pd do you remember this your dad gave you 20 okay heat
your dad gave you 20 okay heat supply to the system i 20 i equal to now now
supply to the system i 20 i equal to now now now now now the entire internal energy
now now now the entire internal energy I went completely and you kept it in your pocket
I went completely and you kept it in your pocket I have put in some blade, Wade is not coming, Papa
I have put in some blade, Wade is not coming, Papa I am standing here now with shaving cream on
I am standing here now with shaving cream on when did you not do any work full
when did you not do any work full work done cunningly is zero only then internal
work done cunningly is zero only then internal Who will all the energy go into?
Who will all the energy go into? will go into heat clear then when the
will go into heat clear then when the internal energy is going to be equal to
internal energy is going to be equal to When the work is going to be equal to 0
When the work is going to be equal to 0 heat will be equal to change in internal
heat will be equal to change in internal Energy will be equal to what you understood
Energy will be equal to what you understood Understand well why mechanical energy can
Understand well why mechanical energy can be completely why mechanical energy can be
be completely why mechanical energy can be completely converted into heat energy but
completely converted into heat energy but Whole heat energy cannot be converted into
Whole heat energy cannot be converted into mechanical energy okay now this is a really good
mechanical energy okay now this is a really good The question arises, why does this happen
The question arises, why does this happen that the whole of
that the whole of all the heat all of us
all the heat all of us we convert mechanical energy into heat
we convert mechanical energy into heat but can absorb all the heat
but can absorb all the heat cannot be converted into mechanical energy
cannot be converted into mechanical energy It is actually not true that you
It is actually not true that you All mechanical energy converted into heat
All mechanical energy converted into heat It is not necessary every time, how many
It is not necessary every time, how many The way you clapped your hands, it was like that for me
The way you clapped your hands, it was like that for me The energy of the hand is heat as well as sound
The energy of the hand is heat as well as sound I am also going so it is not like this every time
I am also going so it is not like this every time would convert all mechanical energy into heat
would convert all mechanical energy into heat I did it but yes it is possible that all
I did it but yes it is possible that all All the mechanical heat gets converted into some
All the mechanical heat gets converted into some in cases like there's a rocket in space
in cases like there's a rocket in space The rocket gets some friction from somewhere
The rocket gets some friction from somewhere I am wondering what is going on there
I am wondering what is going on there But sound cannot be produced
But sound cannot be produced It's not getting done there, the whole thing
It's not getting done there, the whole thing What is the energy going into there? It's going into heat.
What is the energy going into there? It's going into heat. Now it is said that I have understood all the heat
Now it is said that I have understood all the heat Why can't we convert it into work
Why can't we convert it into work Because when it is heat, son there is a lot of heat
Because when it is heat, son there is a lot of heat All the heat gets lost as you
All the heat gets lost as you If heat makes someone warm, is it actual?
If heat makes someone warm, is it actual? As you suppose it is a cooker, you can call it a cooker
As you suppose it is a cooker, you can call it a cooker If you are giving out heat, is that heat energy directly
If you are giving out heat, is that heat energy directly The cooker is not getting all the gas
The cooker is not getting all the gas heating up on its own after heating up
heating up on its own after heating up The cooker is heating up the atmosphere as well
The cooker is heating up the atmosphere as well The gas around it gets heated because
The gas around it gets heated because what is a cooker what is a cooker
what is a cooker what is a cooker what is that cooker doing radiating also
what is that cooker doing radiating also It is generating a lot of heat energy
It is generating a lot of heat energy If loss happens in the atmosphere then it is
If loss happens in the atmosphere then it is The impossible is not possible when you pass gas
The impossible is not possible when you pass gas If you are giving all the gas to the cooker then
If you are giving all the gas to the cooker then The cooker gets all the gas that you give it
The cooker gets all the gas that you give it all the energy goes to the gas and then
all the energy goes to the gas and then After that make all the gas work with it
After that make all the gas work with it It is not impossible because the loss is huge
It is not impossible because the loss is huge will go son, do you understand like this
will go son, do you understand like this what kind of question is this is such a question that when I
what kind of question is this is such a question that when I When I wear earphones then it happens like this in the earphones
When I wear earphones then it happens like this in the earphones It happens that whatever someone else says gets transmitted directly to me
It happens that whatever someone else says gets transmitted directly to me It is going in my ear but I am using such a micro
It is going in my ear but I am using such a micro Why can't Mike figure out what I'm up to?
Why can't Mike figure out what I'm up to? I should also say that it should only be used in earphones
I should also say that it should only be used in earphones it doesn't happen because whenever you are speaking
it doesn't happen because whenever you are speaking Something or the other will go out from here
Something or the other will go out from here A person is standing and you have put on earphones
A person is standing and you have put on earphones If you take it then it is possible that whatever the other person says
If you take it then it is possible that whatever the other person says it is happening only you should hear it
it is happening only you should hear it Don't let it happen, whatever earphones you wear
Don't let it happen, whatever earphones you wear The person in front of you is speaking somewhere over there
The person in front of you is speaking somewhere over there If the person is talking to you on the phone from far away
If the person is talking to you on the phone from far away You can hear his voice only when you speak
You can hear his voice only when you speak So he will be able to hear it, at least he will be able to hear it a little
So he will be able to hear it, at least he will be able to hear it a little will give it just beside you and you will say something like this
will give it just beside you and you will say something like this put the machine on your mouth so that you can hear something
put the machine on your mouth so that you can hear something do you understand will give in the same way whenever
do you understand will give in the same way whenever Half of you are trying to get work out of the heat
Half of you are trying to get work out of the heat you are giving the heat of the cooker to someone and
you are giving the heat of the cooker to someone and If you want to do work then heat loss
If you want to do work then heat loss like when we speak then the sound
like when we speak then the sound There is a loss, do you understand that they are a little
There is a loss, do you understand that they are a little
This particular thing is clear, now let's talk about it
this is the of state ok clear now on this said that the following cannot
said that the following cannot
is sorted then we can consider three types of graphs will study about pavi pati andti now
will study about pavi pati andti now
we can write delta t b a 2 exactly we can because we have n a b 2 delta t
we can because we have n a b 2 delta t if you write it then it will be the same thing because this
if you write it then it will be the same thing because this
is it pav or p final or should I write it like this p2 v2 minus p1 vv son did you understand p2 v2
v2 minus p1 vv son did you understand p2 v2
Brother Okey Ediya Betic Process has higher slope
Okey Ediya Betic Process has higher slope then can two isothermal curves intersect
then can two isothermal curves intersect
It is isothermal, son, remember isothermal
about the process yes we got edia betic know about the process that adia
know about the process that adia The equation of the Betic process is called
The equation of the Betic process is called we write p v to the power gamma e e to
we write p v to the power gamma e e to
What is the second law of thermodynamics Thermodynamics is nothing but the second law
Thermodynamics is nothing but the second law This is Lappu's law, now look at the second law here
This is Lappu's law, now look at the second law here There are two statements of thermodynamics
There are two statements of thermodynamics Basically the second law of thermodynamics is
Basically the second law of thermodynamics is says that you can use the heat to its fullest extent
says that you can use the heat to its fullest extent This basic basic
This basic basic We know its outline or not
We know its outline or not You can do it because brother you will lose something
You can do it because brother you will lose something It will definitely happen by doing classification here
It will definitely happen by doing classification here this is Max who is Kelvin Planck and
this is Max who is Kelvin Planck and These two people are classier and gave statements
These two people are classier and gave statements
