The heat capacities for the ideal gas state depend upon the_________________?
Correct answer: B. Temperature
- A. Pressure
- B. Temperature
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
For an ideal gas, enthalpy and internal energy depend only on temperature, so Cp and Cv are functions of temperature. Pressure does not affect ideal-gas heat capacities.
