With the increase in temperature, solubility of gases in liquid decrease.
Option A
<h3><u>Explanation:</u></h3>
Gases are soluble in liquid but it's solubility depends on temperature and pressure. As the temperature increases, the solubility of gases decrease. It is because with the increase in temperature, the kinetic energy of both the molecules of gas and the solvent increase. This leads to increase in molecular vibration and this makes the gas molecules escape the solution.
This makes the gas solubility vs temperature graph have a hyperbolic curve. As the temperature increases the solubility decrease and vice versa.
