Verified step by step guidance1
Understand that diffusion is the process by which particles spread from an area of high concentration to an area of low concentration.
Recall that temperature is a measure of the average kinetic energy of particles in a substance.
Recognize that as temperature increases, the kinetic energy of the particles also increases, causing them to move more rapidly.
Consider that with increased particle movement, the rate at which particles spread out or diffuse also increases.
Conclude that the rate of diffusion increases with an increase in temperature due to the higher kinetic energy and faster movement of particles.
