Well, is it possible for heat to flow between two objects with same total internal energy? the answer is yes.
00:14
Let's understand this point.
00:17
Let's say we have two objects, object a and object b.
00:25
Object b.
00:29
Object a is greater than object b in size.
00:34
It's clear from the picture and let's say that the internal energy which is represented by ua is equal to the total internal energy of object b the question is will heat flow between object a and object b these two objects have equal total internal energies well the object b is smaller than object a, object b has got less number of particles or less number of molecules is compared to the molecules of object a.
01:23
Now, it is possible that the temperature of object b, the temperature of object b is greater than the temperature of object a.
01:41
Only in this condition these two objects can have equal total internal energies because the size of object b is smaller than the size of object a.
01:54
We know that the total internal energy is to grant some of kinetic and potential energies.
02:03
Since object b is smaller in size is compared to object a, if its total internal energy is equal to the object, then it is only possible if its temperature is greater than the temperature of object a therefore heat will flow from object a, heat will flow from object sorry not a from object b to object a because the temperature of b is greater than the temperature of a although the total internal energies of both objects are equal now let's come to the second point.
02:48
Is it possible for heat to flow from an object that has less total internal energy to an object which has more total internal energy? let's say this is object a and this one is object b.
03:15
All right.
03:17
Let's say in this case the total internal energy of object b is greater than the total internal energy of object a right now this object b is greater than object a right now let's say the temperature of object a is represented by t a and the temperature of object b is represented by tb...
