Internal pressure of a perfect gas (ideal gas) is :
Text Solution
Verified by ExpertsThe correct answer is:
A
In a perfect gas is no energy of interaction between the molecules of the gas, so change the distance between the molecular by changing the volume of the gas cannot affect the internal energy of the gas. U is independent of V. Hence internal pressure is zero.
