A certain ideal gas has an adiabatic coefficient of ê = 4/3. What is its molar specific heat at constant pressure?

Question

Quizplus · Accepted Answer

The adiabatic coefficient is given by the ratio of the specific heat at constant pressure to the specific heat at constant volume. For an ideal gas, the specific heat at constant volume is given by (3/2)R, where R is the gas constant. Therefore, the specific heat at constant pressure is given by:Cp = ê * Cv = (4/3) * (3/2)R = 2RTherefore, the molar specific heat at constant pressure is 2R.
