Equal amounts of heat are supplied to equal masses of helium and oxygen, kept at the same initial temperature. If `T_(He)andT_(O)` denote the increase in temperatures of helium and oxygen, then

Two tanks of equal volumes contain equal masses of hydrogen and helium at the same temperature. Then :

Equal masses of helium and oxygen are mixed in a container at 25 C^(@) . The fraction of the total pressure exerted by oxygen in the mixture of gases is

Consider the four gases hydrogen, oxygen, nitrogen and helium at the same temperature. Arrange them in the increasing order of the de Broglie wavelengths of their molecules.

The mean speed of the molecules of a hydrogen sample equals the mean speed of the molecules of a helium sample. Calculate the ratio of the temperature of the hydrogen sample to the temperature of the helium sample.

X and Y are two cylinders, fitted with frictionless pistons. Both of them contain equal amounts of oxygen at 200K. Equal amount of heat is given to the gas in each cylinder. However, the piston of A is fixed while that of B is movable. What is the rise in temperature of the gas in B, if the rise in temperature of A is 42 K ?

Assetion : Equal masses of helium and oxygen gases are given equal quantities of heat. The rise in temperature of helium is greater thant that in case of oxygen. Reason : The molecular mass of oxygen is more than molecular mass of helium.
