Dissolving Speed - Effect of Temperature Changes

One of the old Intermediate 1 PPAs

When a substance dissolves in a liquid it forms a solution. In this experiment the substance used will be sugar crystals and the liquid will be water.

The aim of the experiment is to find out how changing the temperature of the water changes the speed at which the sugar dissolves.

To make the experiment fair, only one factor – the temperature of the water – will change.

Other factors like the volume of water, the mass and size of the sugar crystals and how much we stir the mixture must be kept the same.
