Soap is made of molecules with atoms that share electrons equally at one end and atoms that have a slight charge at the other end. which could be soluble in soap?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
