To investigate how different factors affect the rate at which a solute dissolves in a solvent.
Temperature
The solute will dissolve more faster in hot solvent because the molecules will move faster.
How hot or cold is the solvent?
I think hot water will dissolve the sugar more- Zaid
How does temperature help the rate of dissolving?
Surface Area
the type of solvent that dissolves the solute
example- salt and sugar dissolves in water
relationship between surface area and rate of dissolving
size of solute
The amount of solid surface used into the solvent.
Stirring
small particles or big particles
fast or slow
How does stirring helps the rate of dissolving?
Solvent- Liquid
Type of solvent
milk
water
soda
oil
petrol
amount of solvent
solute- solid
Type of solute
coffee
pepper
sugar
salt
pebbles
solution- mixture of solute and solvent
Steps of investigation
