Reducing the pressure from $$1.0$$ atm to $$0.5$$ atm would change the number of molecules in one mole of ammonia to?

A quantity of $$10$$g of a gas at $$1$$ atm pressure is cooled from $$273^o$$C to $$273$$K keeping its volume constant, the final pressure of the gas will be?

At what temperature the $$KE$$ of gas molecule is half that of its volue at $$27^oC$$?

The average translation kinetic energy of $$O_2$$ (molar mass $$32$$) molecules at a particular temperature is $$0.048\ eV$$. The translational kinetic energy of $$N_2$$ (molar mass $$28$$) molecules in $$eV$$ at the temperature is :

The heat capacity of air is $$20\ J/K/$$mol. The amount of heat, required to heat the room through $$1^o$$, assuming the amount of air in the room to be $$29\ kg$$, is

The energy density U / V of an ideal monoatomic gas is related to its pressure P as

The curve in figure represents potential energy(U) in between two atoms in a diatomic molecule as a function of distance 'x' between atoms. The atoms are:

The ratio of average translational kinetic energy to rotational kinetic energy of a diatomic molecule at temperature $$T$$ is :
