How does solubility change with temperature for gases?

Answer 1

The solubility of gas in a liquid depends primarily on the (a) Temperature of the liquid (b) nature of the gas. The gases are more soluble in water at lower temperature, as the temperature of the liquid increases gases become lesser soluble in water.

(b) Polar gases are more soluble in polar solvents, non polar solvents dissolves non polar gases. Ammonia is a polar gas, it dissolves in polar solvent like water. Non polar gases like methane strongly dissolves in non polar solvents like benzene.

Solubility of gases generally decreases with increasing temperature because as temperature rises, the kinetic energy of gas molecules increases, leading to greater molecular motion and decreased attraction between gas molecules and solvent molecules, resulting in lower solubility.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
