A vessel contains `N` molecules of an ideal gas. Dividing mentally the vessel into two halves `A` and `B`, find the probability that the half `A` contains `n` molecules. Consider the cases when `N = 5` and `n = 0,1,2,3,4,5`.

A vessel contains N molecules of a gas at temperature T. Now the number of molecules is doubled, keeping the total energy in the vessel constant. The temperature of the gas is

A vessel of volume V_0 contains N molecule of an ideal gas. Find the probability of n molecules getting into a certain separated part of the vessel of volume V . Examine, in particle, the case V = V_0//2 .

When a solid containing 10 N^@ molecules is allowed to melt, then

The N_(2)H_(4) molecule contains :

The N_(2)H_(4) molecule contains :

A vessel contains a mixture of one of oxygen and two moles of nitrogen at 300K The ratio of the average rotational kinetic energy per O_(2) molecule to N_(2) molecule is .

Two identical vessels contain two different ideal gases at the same temperature. If the average speed of gas molecules in the first vessel is euqal to the most probable speed of molecules in the second vessel, then the ratio of the mass of gas molecules in the first vessel to that in the second vessel is

Two identical vessels contain two different ideal gases at the same temperature. If the average speed of gas molecules in the first vessel is euqal to the most probable speed of molecules in the second vessel, then the ratio of the mass of gas molecules in the first vessel to that in the second vessel is

A 5 L vessel contain 2.8 g of N_2 when heated to 1800 K, 30% molecules are dissociated into atoms
