inorganic chemistry - Why won't increasing the temperature increase the solubility of a gas in a liquid solvent?


If I raise the temperature of a solution of a gas in a liquid solvent, why won't the solubility increase?


Increasing the pressure will increase the solubility, but increasing the pressure doesn't mean increasing the temperature? What is wrong with this argument?
