Solubility and Temperature

My topic is the effect of temperature on solubility.
Solubility is the degree to which a substance dissolves in a solvent to make a solution.

The effect of temperature on the solubility of a substance in water depends on the type of substance.Generally:
     The solubility of a gas in water increases as the temperature of the water decreases.
     The solubility of carbon dioxide in water is graphed below.

solubility diagram - carbon dioxide - CO2 - in water at different temperatures                                                             The solubility of a solid in water increases as the temperature of the water increases.
There isn't a set trend for the effect of temperature on the solubility of liquids in water.
To fully test the effect of temperature on solubility I'll need a solid, liquid and gas which are soluble in water.
