Question

Molar heat capacity of a gas does not depend on.

• A. Its temperature
• B. Its molecular weight
• C. Its atomicity
• D. The conditions under which heat is supplied

Answer 1

Answer: (A)

Its temperature

The heat capacity specifies the heat needed to raise a certain amount of a substance by 1 K. For a gas, the molar heat capacity C is the heat required to increase the temperature of 1 mole of gas by 1 K. Important: The heat capacity depends on whether the heat is added at constant volume or constant pressure.

Hence the Molar heat capacity does not depends on its temperature or say gas temperture
