The specific heat of $1$ mole of an ideal gas at constant pressure $({C_P})$ and at constant volume $({C_V})$ which is correct
A${C_P}$ of hydrogen gas is $\frac{5}{2}R$
B${C_V}$ of hydrogen gas is $\frac{7}{2}R$
C${H_2}$ has very small values of ${C_p}$ and ${C_V}$
D${C_p}$ -${C_v}$ $= 1.99 \,cal/mole-K$ for ${H_2}$

A mixture of ideal gases has $2$ moles of He, $4$ moles of oxygen and $1$ mole of ozone at absolute temperature $T$. The internal energy of mixture is ............. $RT$
A gas at absolute temperature $300\,K$ has pressure $= 4 \times 10^{-10}\,N /m^2$ . Boltzmann constant, $k = 1.38 \times 10^{-23}\,J / K$ . The number of molecules per $cm^3$ is of the order of
One mole of an ideal monatomic gas undergoes a process described by the equation $PV^3 =$ constant. The heat capacity of the gas during this process is
Assertion $(A):$ The total translational kinetic energy of all the molecules of a given mass of an ideal gas is $1.5$ times the product of its pressure and volume.
Reason $(R):$ The molecules of gas collide with each other and the velocities of the molecules change due to the collision.
$Assertion :$ The ratio of $\frac{C_p}{C_v}$ for an ideal diatomic gas is less than that for an ideal monoatomic gas (where $C_p$ and $C_v$ have usual meaning).
$Reason :$ The atoms of a monoatomic gas have less degrees of freedom as compared to molecules of the diatomic gas.
