What should be done to speed up diffusion?

Diffusion is the phenomenon of mixing two substances. This process is caused by the fact that the molecules of one substance penetrate into the gaps between the molecules of another and form a mixture.

Let’s analyze the possible answers. The presence or absence of light does not affect the movement of molecules. Reducing the contact area will also not have a positive effect on the acceleration of diffusion. The remaining option is temperature. Recall that the temperature of a substance affects the speed of movement of molecules: the higher it is, the faster the molecules move. Consequently, the high temperature will accelerate the diffusion.
