A) The pressure of a gas is due to collision of the gas molecules with the walls of the container.
B) The molecular velocity of any gas is proportional to the square root of the absolute temperature.
C) The rate of diffusion of a gas is directly proportional to the density of the gas at constant pressure.
D) Kinetic energy of an ideal gas is directly proportional to the absolute temperature
Correct Answer: C
Solution :
he rate of diffusion is inversely proportional to the square root of the density at constant pressure. Rate of diffusion \[\propto \frac{1}{\sqrt{Density}}\]
