Question

On heating diffusion becomes faster . Why ?

Answer 1

when we heat somthing, the kinetic energy of the particles in the object that we heat is increased. due to this increase in kinetic energy, the particles starts to move faster. when the particles move faster, diffusion takes place faster than in normal temperature.

Answer 2

On heating kinetik energy of particles became more so they move faster and by moving faster , diffusion becomes faster
