Question

define diffusion . explain with an example that temp affect the rate of diffusion

Answer 1

Diffusion means movement of particles through material.  Diffusion is important in physics, chemistry and biology.  Diffusion is affected by temperature, the size (mass) of the particles that are moving, and the thickness (viscosity) of the environment in which they are moving.  Temperature is a measure of kinetic energy.  Diffusion is affected by this kinetic energy.  Basically, increasing the temperature increases the molecules speed (kinetic energy) and decreasing it decreases the speed.

Answer 2

the rate intermixing of particles by their own is diffusion.yes temp affects the rate of diffusion because temp increase the kinetic energy of the particles which is responsible for the increment in rate of diffusion
