Question

For one mole of an ideal gas, which of these statements must be true?
(a) Internal energy (U) and enthalpy (H) each depends on temperature.
(b) Compressibility factor Z is not equal to 1.
(c) 
(d)  for any process

Canvas Classes · Accepted Answer

Strategy:
 Recall the unique properties of an ideal gas regarding state functions and constant pressure/volume relationships.

Step 1: Evaluate Statements
- (a): For an ideal gas, internal energy () and enthalpy () are functions of temperature only. (True)
- (b): For any ideal gas, the compressibility factor  is exactly . Statement (b) says . (False)
- (c):  is Mayer's relation. (True)
- (d):  holds for an ideal gas for any process because  is independent of  and  at constant . (True)

Step 2: C
