Dissolving is when particles collide and break substances down, for example sugar, when particles gain heat they gain engery and collide with sugar particles, also i the concentration of the solvent is doubled it doubles the rate of the reaction. In that reactionthe solvent, the water, breaks the solute down, the sugar, after this happens the soluteand the solvent mix to become a solution.

There are several variables that could affect the rate of dissolving eg: Tempreture. If you raise the tempreture the particles gain energy and collide with the solute more, therefor increasing the chance of a succesful collision. If you increase the concentration of the solvent there are more particles to collide with the solute, therefor increasing the rate of the reaction by increasing the rate of succesful collisions.

For my investigation I have chosen to investigate the rate of a reaction when the tempreture...
