In the given question we have been provided that for an ideal gas, del u over del v, del u over del v for a constant temperature is zero.
00:12
Okay, this is for ideal gas.
00:15
We have to prove, we have to prove that del cv over del v for a constant temperature is also zero.
00:27
Okay, so how we can do that? we know that cv is given as del u over del t.
00:34
Okay, so differentiating with respect to volume on both side, we will get what we will get c.
00:44
Del cv over del v, okay, and at constant temperature, okay, at constant temperature.
00:54
So this will be del cv over del v on the left and side.
00:58
And in the right hand side we will have del u, del t over del v at a constant temperature...
