As temperature increases, the rate of diffusion also increases.

Diffusion is a form of passive transport during which particles travel down a concentration gradient. In other words, particles travel from an area of higher concentration to an area of lower concentration.

As temperature increases, the rate of diffusion also increases.

Diffusion is a form of passive transport during which particles travel down a concentration gradient. In other words, particles travel from an area of higher concentration to an area of lower concentration.

Temperature is a measurement of the average kinetic energy of the particles that make up a substance. Kinetic energy is the energy of motion. Thus, an increase in the temperature of a substance implies that the average kinetic energy of the particles of the substance has increased. As the kinetic energy of the particles increases, the particles begin to move faster and more often. Thus, the rate at which the particles diffuse and move from an area of higher concentration to an area of lower concentration will also increase.
