Question

The heat capacity at constant volume of an ideal gas depends on: Select one: a. The number of molecules b. Temperature c. None of the options shown d. The volume e. The pressure

Answer 1

heat capacity at constant volume is related to the heat require by a gas to raise its temperature by dT is given by

dQ = n Cv dT

since volume is constant, therefore the heat is stored in the form of internal energy and we know that internal energy is state function of temperature which means the internal energy does not depends on the path followed to reach the final state but solely depends on the final state of the system (no matter how that state have been reached/achieved).

Therefore, the heat capacity at constant volume depends on temperature.
