List of top Physics Questions on kinetic theory asked in NEET (UG)

The temperature of a gas is -50° C. To what temperature the gas should be heated so that the rms speed is increased by 3 times?

The mean free path for a gas, with molecular diameter $d$ and number density $n$ can be expressed as :

At what temperature will the rms speed of oxygen molecules become just sufficient for escaping from the Earth�s atmosphere ? (Given: Mass of oxygen molecule $(m) = 2.76 \times 10^{-26} kg $ Boltzmann�s constant $k_B = 1.38 \times 10^{-23} J \, K^{-1}$)

A gas mixture consists of $2$ moles of oxygen and $4$ moles of Argon at temperature T. Neglecting all vibrational modes, the total internal energy of the system is

Two vessels separately contain two ideal gases $A$ and $B$ at the same temperature, the pressure of $A$ being twice that of $B$. Under such conditions, the density of $A$ is found to be $1.5\, times$ the density of $B$. The ratio of molecular weight of $A$ and $B$ is :

An electron moves in a circular orbit with a uniform speed v. It produces a magnetic field B at the centre of the circle. The radius of the circle is proportional to:

To find out degree of freedom, the correct expression is:
