Question

What happens when the temperature of a solution increases?

Answer 1

What happens depends on the nature of the interaction between the solute and the solvent.

Explanation:

In most solid liquid solutions solubility increases. those that are endo thermic heat is a reactant so an increase in temperature drives the reaction forward.
However in some solid liquid solutions that are exothermic heat is a product and therefore the solubility will decrease.

Also gas liquid solutions usually decrease in solubility. increasing temperature will decrease the amount of carbon dioxide in solution.
The ice cold coke will have more fiss than a warm coke.
