According to Henry's law of solubility, on increasing the pressure of gas above the liquid, concentration of the gas in solution also increases which means solubility of gas in liquid increases with increase of pressure.
Moreover, solubility of a gas in liquid also increases with the lowering of temperature. Actually, increase in temperature increases the kinetic energy as well. The higher kinetic energy leads to more motion/movement in the molecules thereby dissociating the intermolecular bonds and ultimately escaping from the solution. Thus, solubility of gas in liquid decreases with increase of temperature and increases with decrease in temperature.
Hence, Solubility of a gas in liquid increases with increase of pressure and decrease of temperature
