Specific heat at constant pressure C_P of a gas

For an ideal gas (C_(p,m))/(C_(v,m))=gamma . The molecular mass of the gas is M, its specific heat capacity at constant volume is :

STATEMENT-1: The specific heat capacity of a gas at constant pressure is always greter than its specific heat capacity at constant volume. STATEMENT-2: Work is done by a gas when it expands.

An ideal gas is made to undergo a process T = T_(0)e^(alpha V) where T_(0) and alpha are constants. Find the molar specific heat capacity of the gas in the process if its molar specific heat capacity at constant volume is C_(v) . Express your answer as a function of volume (V).

If M is the molecular weight of gas then the principal specific heat of a gas is given by

The ratio of specific heat capacity at constant pressure to the specific heat capacity at constant volume of a diatomic gas decreases with increases in temperature . Explain

During an adiabatic process of an ideal gas, if P is proportional to (1)/(V^(1.5) , then the ratio of specific heat capacities at constant pressure to that at constant volume for the gas is
