Question

At same temperature and pressure of an ideal gas, ____________.

Options

• the molar specific heat at constant pressure is the same for all gases.

• the molar specific heat at constant volume is the same for all gases.

• the ratio of the molar specific heats at constant volume and at constant pressure is the same for all gases.

• the difference between the molar specific heats at constant pressure and at constant volume is the same for all gases.

Answer 1

At same temperature and pressure of an ideal gas, the difference between the molar specific heats at constant pressure and at constant volume is the same for all gases.
