Two gases, a monatomic and a diatomic gas, are at the same temperature. The ratio of their molar specific heats at constant volume ($C_v$) is:

What is the ratio of specific heats of constant pressure and constant volume of $N{H_3}$ is

Two flasks at the same temperature contain ideal gases, gas A and gas B. The pressure in the flask with gas A is five times the pressure in the flask with gas B. The density of gas A is found to be four times the density of gas B. What is the ratio of the molecular weight of gas A to gas B?

The ratio of specific heats (γ) for a monoatomic ideal gas is:

If the degree of freedom of a gas are $f,$ then the ratio of two specific heats ${C_P}/{C_V}$ is given by

If one mole of a monoatomic gas $\left( {{\rm{\gamma }} = \frac{5}{3}} \right)$ is mixed with one mole of a diatomic gas $\left( {{\rm{\gamma }} = \frac{7}{5}} \right)$, the value of ${\rm{\gamma }}$ for the mixture is

The gases carbon-monoxide (CO) and nitrogen at the same temperature have kinetic energies ${E_1}\;{\rm{and}}\;{E_2}$ respectively. Then

A gas mixture consists of 2 moles of ${{\rm{O}}_2}$ and 4 moles of $Ar$ at temperature $T$. Neglecting all vibrational modes, the total internal energy of the system is

For a gas $\gamma = 7/5.$ The gas may probably be

At a constant temperature, two separate containers hold ideal gases, gas 1 and gas 2. The pressure of gas 1 is twice that of gas 2. The density of gas 1 is 1.5 times the density of gas 2. What is the ratio of the molecular weight of gas 1 to the molecular weight of gas 2?

Two identical containers hold two different ideal gases, P and Q, at the same temperature. The pressure of gas P is four times the pressure of gas Q. If the density of gas P is found to be 2.5 times the density of gas Q, determine the ratio of the molecular weights of P and Q.
