Are More Soluble at Low Temperatures and High Pressures

CASES ARE MORE SOLUBLE AT LOW TEMPERATURES AND HIGH PRESSURES 

The solubility of a gas in a liquid also depends on the pressure of the gas immediately above the liquid. In general, a higher gas pressure above the liquid 

The solubility of sodium nitrate is 165 grams per 100 milliliters of water at 100°C but only 87 grams per 100 milliliters at 20°C. Cooling a 100°C saturated solution of NaNO, to 20°C causes 78 grams of the solute to precipitate.
