Partial pressure decreases as temperature decreases.
When temperature decreases
--> kinetic energy of the molecules decreases
--> less likely to overcome Van der Waal forces
--> stay in solution more
--> less partial pressure
In a mixture of gases, the pressure exerted by each gas is the same as that which it would exert if it alone occupied the container.
At a particular temperature, the amount of a given gas dissolved in a given liquid is directly proportional to the partial pressure of the gas in equilibrium at the surface of the liquid.
Thus,
