Physics - Heat & Thermo Question with Solution | TestHub

Molecules of a gas are in incessant random motion colliding against one another and with the walls of the container.

The gas is not isotropic and the constant (1/3) in equation $P=\frac{1}{3}\rho v_{rms}^2$ is a result of this property.

The time during which a collision lasts is negligible compared to the time of free path between collisions.

There is no force of interaction between molecules among themselves or between molecules and the wall except during collision.
