Explain the effect of heat on the rate of diffusion.

Open in App

Solution

Diffusion is the process of intermixing particles of different types of matter (solids, liquids, and gases).
Diffusion causes the particles to move from a region of high concentration to a lower concentration.
Gases show the maximum rate of diffusion while solids show the least rate of diffusion.
On increasing the temperature or supplying heat, the particles of gases gain energy and start moving with more velocity.
Hence, increasing temperature increases the rate of diffusion.
