In gases of diatomic molecules,the ratio of the two specific heats of gases ${C_P}/{C_V}$ is

One mole of an ideal monatomic gas requires $210 \, J$ of heat to raise the temperature by $10 \, K$ when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by $10 \, K$,then the heat required is ....... $J$.

What is the ratio of specific heats at constant pressure and constant volume for $NH_3$?

For a gas,$R/C_V = 0.67$. What kind of molecules is this gas made of?

The heat required to raise the temperature of $5$ moles of $O_2$ from $10\,^{\circ}C$ to $20\,^{\circ}C$ at constant volume is ....... $cal$. Given: $C_p = 7.2\,cal/mol/^{\circ}C$ and $R = 2\,cal/mol/^{\circ}C$.

The molar specific heat of an ideal gas at constant pressure and constant volume is $C_{p}$ and $C_{V}$ respectively. If $R$ is the universal gas constant and the ratio of $C_{p}$ to $C_{V}$ is $\gamma$,then $C_{p}$ is equal to:
