Question

state the effect of temperature on diffusion

Answer 1

Temperature has a major effect on diffusion. As temperature increases the rate of diffusion also increases as the kinetic energy increases when the temperature increases. Rate of diffusion decreases as the temperature decreases as the kinetic energy too decreases.

Answer 2

if we increase the temperature if any object/substance its molecules starts moving faster as a result the inter-moleculer force get weak and change the state of the object.
e.g - if we start heating water its molecules starts moving faster and at a given temperture its state changes to vapour.
