Answer:
Increased Temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the molecules which break intermolecular bonds and escape from solution.
According to Le Chatlier's principle, when temperature increases, backward reaction take place in the case of exothermic reactions. So, dissolution of solute(gas) is hindered in high temperatures and is the reason for more solubility of gases in cold water than warm water.
In exothermic reactions, increasing temperature decreases the solubility of the solute. This is because heat energy is released when the solute dissolves in solution. So according to Le Chatelier's Principle, the system will adjust to this excess in heat energy by inhibiting the dissolution reaction.
Therefore , the solubility of a substance decreases on an increase in temeprature in an exothermic reaction.
