Question

Why does the rate of diffusion become faster on heating?​

Answer 1

Answer:

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.

Explanation:

The speed of a molecule is proportional to the square root of the absolute temperature and temperature is the measure of the average kinetic energy of molecules in an object, therefore when the temperature increases the molecules will have more kinetic energy, so they move faster and due to more spontaneous spreading ...
