According to the kinetic theory of gases, the pressure exerted by a gas is due to:

What is the average thermal energy of a single atom in a sample of helium gas at a temperature of $T$ Kelvin? (Helium is a monoatomic gas, and $k_B$ is the Boltzmann constant)

Which of the following correctly represents the relationship between the de-Broglie wavelength ($\lambda$) of a neutron in thermal equilibrium and its mass ($m$) at a constant temperature?

If the mean free path of atoms is doubled then the pressure of gas will become

A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is

At what temperature is the average kinetic energy of a gas molecule equal to the average kinetic energy of the same molecule at 27°C?

What is an ideal gas?

Relationship between $P,V,$ and $E$ for a gas is

In a certain region of space there are only 5 molecules per ${\rm{c}}{{\rm{m}}^2}$ on an average. The temperature there is 3 K. The pressure of this dilute gas is ($k = 1.38 imes {10^{ - 23}}\;{\rm{J}}{{\rm{K}}^{ - 1}})$)

The equation of state of a gas is given by $\left( {P + \frac{{a{T^2}}}{V}} \right){V^c} = \left( {RT + b} \right),$ where $a,b,c$ and $R$ are constants. The isotherms can be represented by $P = A{V^m} - B{V^n},$ where $A$ and $B$ depend only on temperature and

The ratio of mean kinetic energy of hydrogen and nitrogen at temperature $300\;K$ and $450\;K$ respectively is
