An increase in temperature increases the rate of dissolution of a solute in a solvent. We can notice this at home by doing simple experimentation. Try dissolving some sugar in a glass of cold water, for example 1 teaspoonful. Then try to dissolve the same amount of sugar in a glass of hot water. One can easily see that it is much easier and much faster to dissolve sugar in hot water.
When heat is...

When heat is added to a substance, the molecules of the substance gain kinetic energy and start moving much faster. Due to the speed of these molecules, the chances of interaction between solute and solvent molecules increases. This causes an increase in the rate of dissolution and we see that solute dissolves much faster in solvents with higher temperature.
Hope this helps.
