Diffusion refers to the process by which molecules
intermingle as a result of their kineticenergy of random motion. Consider two containers of gas A and B
separated by a partition. The molecules of both gases are in constant motion
and make numerous collisions with the partition. If the partition is removed as
in the lower
The tendency toward diffusion is very strong even at room temperature because of the high molecular velocities associated with the thermalenergy of the particle
