Define diffusion and state the effect of temperature on diffusion.
[2 Mark]

Answer 1

The phenomenon of intermixing of particles of two different types of matter on their own is called diffusion.

When the temperature increases, the rate of diffusion also increases.
At higher temperature, the particles have high kinetic energy. Due to this, they move faster and hence, rate of diffusion increases.
