JEE 2020 Revision :Kinetic Theory of Gaseous

If 𝒱_rms = root mean square speed of molecules,

𝒱_av = average speed of molecules.

𝒱_mp = most probable speed of molecules,

𝒱 = speed of sound in a gas

Then, identify the correct relation between these speeds.

If one mole of a monatomic gas (γ = 5/3) is mixed with one mole of a diatomic gas (γ = 7/5), the value of γ for the mixture is :

Which of the following quantities is the same for all ideal gases at the same temperature ?

When an ideal diatomic gas is heated at constant pressure the fraction of the heat energy supplied which increases the internal energy of the gas is:

The ratio of two specific heats of CO is

Two vessels having equal volume. One vessel contains hydrogen molecules and other contains helium at one atmospheric pressure. If both samples are at the same temperature, the mean speed of hydrogen molecules are –
