For one mole of an ideal gas, which of these statements must be true?
A)

U\,\,\mathrm{ and}\,\,\mathrm{ }H

each depends only on temperature
B) Compressibility factor Z is not equal to 1.
C)

{C_{p,\,\,m}} - {C_{V,\,\,m}} = R

dU = {C_V}dT

for any process.

View answer and explanation

Correct option: C

A, C and D

Option C (A, C and D) is correct because for one mole of an ideal gas, U and H depend only on temperature,

{C_{p,\,m}} - {C_{V,\,m}} = R

, and

dU = {C_V}dT

for any process.
