Question

On heating diffusion becomes faster. Why does this happen​

Answer 1

Upon increasing temperature the kinetic energy of the particles increases, as a result the particles start moving with high speed and intermix more rapidly with each other and so the rate of diffusion increases with heating.

Answer 2

On heating diffusion becomes faster as the intermolecule space between the particles increases and the kinetic energy between the molecules also increases. So the molecules roam around in a faster manner ...that is the reason for the above mentioned condition.
