Explanation:
Detailed explanation-1: -How does changing the type of sugar used affect the time it takes to dissolve? Independent variable: The time that is taken for all of the sugar to dissolve. This is the dependent variable. Dependent variable: If we use caster sugar or icing sugar, the type of sugar.
Detailed explanation-2: -Temperature. Heating up a solvent gives the molecules more kinetic energy. The increased rapid motion means that the solvent molecules collide with the solute with greater frequency, and that the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
