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

The ratio of molar specific heats of oxygen is

The specific heat of a gas at constant volume is $21.2 \, J/mol/^{\circ}C$. If the temperature is increased by $1^{\circ}C$ keeping the volume constant,the change in its internal energy will be ...... $J$.

The equation of a certain gas can be written as: $\left( \frac{T^7}{P^2} \right)^{1/5} = \text{constant}$. The specific heat at constant volume of this gas is (in $\text{J/mol K}$): (in $R$)

The specific heat at constant volume for the monoatomic argon is $0.075 \, kcal/kg-K$,whereas its gram molecular specific heat $C_V = 2.98 \, cal/mole/K$. The mass of the argon atom is (Avogadro's number $= 6.02 \times 10^{23} \, molecules/mole$)

One mole of an ideal monoatomic gas is heated at a constant pressure from $0^{\circ} C$ to $100^{\circ} C$. The change in the internal energy of the gas is (Given, $R = 8.32 \text{ J mol}^{-1} \text{ K}^{-1}$):
