Question

what is meant by diffusion , what is the effect of temperature on diffusion

Answer 1

Temperature and diffusion have a direct relationship. An increase in temperature increases the speed at which molecules move at. An increased speed will yield faster and more even diffusion. A decrease in temperature will cause molecules to slow down. This will slow diffusion and make the spread of molecules less even.

Answer 2

diffusion is a process in which a substance pas from one medium to another.
when the temperature in increased the process of diffusion increases with faster rate.

hope this helps
