As the temperature of the water increases, its vapour pressure increases, meaning there is more water molecules leaving the surface than before.

Gases have weak intermolecular forces and therefore high vapour pressures and will therefore be readily evaporating already.

The increased presence of water vapour above the water (i.e. increased humidity) reduces the amount of the gas able to condense back into the liquid, meaning less gas is dissolved.

Because with an increase in temperature, the solvent molecules have more kinetic energy. This makes it more difficult for a gaseous solute to remain insolutionbecausethesolutemolecules are literally ejected by the high energy solvent molecules.

It takes energy to break bonds, so by heating the solvent, the energy needed to make the gas atoms or molecules in solution more mobile is provided. The solubility of the gas decreases.

According to Le Chaterlee's principal,as the temperature is increased,equilibrium shifts backward,so as the temp is increased,the solubility also decreases.

It doesn't. In general solubility of gases decrease as temperature increases.


How do you increase the solubility of a solution?

The term 'solubility of a solution' is meaningless. Perhaps you mean how do you increase the solubility of a solute in a solvent? In that case, if your solute is a solid, increase the temperature, and if it is a gas, decrease the temperature.
