Obtain the value of $\frac{C_P}{C_V}$ for a non-linear triatomic gas.

The ratio of the adiabatic to isothermal elasticities of a triatomic (non-linear) gas is

$50 \, cal$ of heat is required to raise the temperature of $1 \, mol$ of an ideal gas from $20^{\circ} C$ to $25^{\circ} C$,while the pressure of the gas is kept constant. The amount of heat required to raise the temperature of the same gas through the same temperature range at constant volume is ........ $cal$ $(R = 2 \, cal / mol \cdot K)$.

$A$ polyatomic gas has $f$ vibrational degrees of freedom,then the ratio of the specific heat at constant pressure to that at constant volume will be

When $40 \ J$ of heat is absorbed by a monatomic gas,the increase in the internal energy of the gas is (in $J$)

If $c_p$ and $c_v$ denote the specific heats (per unit mass) of an ideal gas of molecular weight $M$,then which of the following relations holds true,where $R$ is the molar gas constant?
