How does temperature affect solubility?

In general an increase in temperature should result in an increase in solubility.
Explanation:
Dissolution is a bond breaking reaction. The particle/particle interactions in the solid state must be broken and energy must be pumped in to accomplish this.
Sometimes, of course, an increase in temperature does not result in increased solubility. Common salt, sodium chloride, shows very little variation in solubility when the temperature is raised.
Solubility of gases in a liquid will decrease if the temperature of the liquid is raised.
