What role does temperature play in diffusion?

Temperature significantly affects the rate of particle movement during diffusion. As temperature increases, the kinetic energy of the molecules also increases, leading to more vigorous motion. This heightened movement means that particles can collide and disperse more rapidly throughout a medium, whether it be a gas or liquid. It enhances the likelihood of molecules moving from areas of high concentration to areas of low concentration, thereby speeding up the diffusion process.

At lower temperatures, molecular movement is less energetic, resulting in slower diffusion rates. Therefore, understanding the relationship between temperature and diffusion is crucial in many biological and chemical processes where the rate of diffusion can have significant implications on reactions and interactions. This is why the option that highlights the impact of temperature on the rate of particle movement is correct.
