When the temperature of a gas is increased,does the degree of freedom change?

If the degrees of freedom of a gas molecule is $6$,then the total internal energy of the gas molecule at a temperature of $47^{\circ} C$ (in $eV$) is (Boltzmann constant $= 1.38 \times 10^{-23} \ J \ K^{-1}$)

What will be the average value of energy for a monoatomic gas in thermal equilibrium at temperature $T$?

Internal energy of $n_1$ moles of hydrogen at temperature $T$ is equal to the internal energy of $n_2$ moles of helium at temperature $2T$. Then the ratio $n_1:n_2$ is: [Degree of freedom of $He = 3$,Degree of freedom of $H_2 = 5$]

The number of translational degrees of freedom for a diatomic gas is

The internal energy of one mole of a rigid diatomic gas at absolute temperature $T$ is
