Kinetic Theory ...

$$2$$ mole ideal He gas and $$3$$ mole ideal $$H_2$$ gas at constant volume find out $$C_v$$ of mixture 

In a jar having a mixture of $$H_{2}$$ and He 

In Maxwell's speed distribution curve, for N2N2K will be?

r.m.s. speed of ideal gas at $$127^oC$$ is $$200m/s$$, the r.m.s. speed of same ideal gas at temperature $$227^oC$$ is:

At constant pressure, the heat of formation of a compound is not dependent on temperature, when: 

Pressure of an ideal gas is increased by keeping temperature constant. The kinetic energy of molecules.

Which row correctly describes the ordering and motion of the molecules in liquid water and in ice when both are at a temperature of $${0}^{o}C$$

A volume of $$2.5\ L$$ of a sample of a gas at $$27^o$$C and $$1$$ bar pressure is compressed to a volume of $$500\ ml$$ keeping the temperature constant, the percentage increase in pressure is?

If the temperature of $$3$$ moles of helium gas is increased by $$2\ K$$, then the change in the internal energy of helium gas is :

In the case of solid, number of degrees of freedom is :
