\\Input Variable

Outcome Variable

Temperature

Time taken for the sugar to dissolve

Volume of Water

Number of Stirs

Amount of Sugar

Type of Sugar

The input variable we are testing is the temperature to see if the time taken for the sugar to dissolve differs.

Prediction

I predict that when the temperature of the water increases, the time taken for the sugar to dissolve in the water will be quicker than dissolving at a low temperature.

This is because, the particles in a solid are very close together and are in a fixed position. The particles in a liquid are very close but are not in a fixed position causing them to flow over each other. So when a solid is put into a liquid, the liquid particles collide with the solid , causing the solid to get smaller and eventually dissolve. As heating the water, the particles will move more and collide more often with the sugar. This will cause the sugar to dissolve quicker.The particles never disappear they just become so broken down that they cannot be seen by the naked eye.

So I think , the sugar will dissolve faster , as the temperature of the water increases.

Aim

My aim is to prove my prediction above.

Apparatus

Heatproof mats

Tripod

Gauze
