Internal pressure of a perfect gas (ideal gas) is:

A

Zero

B

infinite

C

Calculated by `PV=nRT`

D

Can not say directally

Text Solution

Verified by Experts

The correct Answer is:
A
In a perfect gas in no energy of interaction between the molecules of the gas, so change the distance between the molecule 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.
