Define free path and mean free path.

Define mean free path .

The diffusion coefficient of an ideal gas is proportional to its mean free path and mean speed. The absolute temperature of an ideal gas is increased 4 times and its pressure is increased 2 times.As a result, the diffusion coefficient of this gas increases x times. The value of x is........

With increase in pressure, the mean free path

If P is doubled and T is reduced to half at constant volume, what will be its effect on the mean free path ( lambda ) of a gas molecule?

Two gaseous molecules A and B are traveling towards each other. Let the mean free path of the molecule be sigma and Z be the collision number with other molecules at pressure 1 atm . Answer the following questions If the mean free path is sigma at 1 atm pressure, then its value at 5 atm pressure is

Assertion : Mean free path of a gas molecule varies inversely as density of the gas. Reason : Mean free path varies inversely as pressure of the gas.

If diameter of gas molecule is d then mean free path is inversely proportional to

An ideal gas in a closed container is slowly heated. As its temperature increases, which of the following statements are true? (A) the mean free path of the molecules decreases. (B)the mean collision time between the molecules decreases. (C ) the mean free path remains unchanged. (D) the mean collision time remains unchanged.

If the volume of a gas is doubled either isothermally or adiabatically, in which case change in mean free path is more.
