Statement I: When an ideal gas is taken ...

Statement I: When an ideal gas is taken from a given thermodynamics state `A` to another given thermodynamic state `B` by any polytropic process, the change in the internal energy of the system will be the same in all processes.
Statement II: Internal energy of the gas depends only upon its absolute tmeperature.

A

Statement I: is true, Statement II is true and Statement II is the correct explanation for Statement I.

B

Statement I: is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Any given thermodynamics state has a definite temperature `T`. The internal energy of a system in an ideal gas is a function of only the absolute temperature and is independent of its pressure and volume . The internal energy per mole of a gas is directly proportional to its absolute temperature.
