Detailed explanation-1: -Increase in temperature means an increase in molecules’ speed (kinetic energy). So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs more quickly.

Detailed explanation-2: -When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.

Detailed explanation-3: -Temperature increase generally increases the diffusivity and therefore the rate of gas emission from coal. Gilliland [8] shows that D is proportional to T 3/2 for elastic sphere–type molecules where T is the absolute temperature.

Detailed explanation-4: -Particles can diffuse over a membrane more quickly when the temperature rises because they have greater kinetic energy. Diffusion, therefore, occurs at a faster pace when the temperature rises.

Detailed explanation-5: -When temperature increases it increases the kinetic energy of particles which results in increasing the rate of diffusion of the particles.
