Solubility of gas in a liquid and its dependence on temperature and pressure is an important concept in chemistry. The solubility of gas in a liquid is determined by various factors such as temperature, pressure, nature of the gas, and the nature of the liquid. However, the most significant factor affecting the solubility of gas in a liquid is temperature.
Temperature and Solubility:
As the temperature of the liquid increases, the solubility of gas in the liquid decreases. This is because the gas molecules gain kinetic energy at higher temperatures and tend to move away from each other, making it easier for them to escape from the liquid. This phenomenon is known as gas evolution. Conversely, at lower temperatures, the kinetic energy of the gas molecules decreases, making it easier for them to dissolve in the liquid. Hence, the solubility of gas in a liquid decreases with increasing temperature.
Pressure and Solubility:
The solubility of gas in a liquid also depends on the pressure exerted on the gas. According to Henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Therefore, the solubility of gas in a liquid increases with increasing pressure. When the pressure above a liquid-gas system is increased, the gas molecules are pushed into the liquid, and the solubility of the gas in the liquid increases. Conversely, when the pressure above a liquid-gas system is decreased, the gas molecules tend to escape from the liquid, and the solubility of the gas in the liquid decreases.
Conclusion:
In conclusion, the solubility of gas in a liquid is mainly influenced by temperature and pressure. The solubility of gas in a liquid decreases with increasing temperature and increases with increasing pressure. These factors play a crucial role in various chemical reactions and processes and are essential for understanding the behavior of gas-liquid systems.

In an equilibrium system of gas dissolved in solvent, when pressure over it is increased more and more gas particles are forced into a smaller volume. This also increases the rate at which they strike the surface of the solvent to enter it. Consequently, more gas dissolves with increasing pressure. In the case of increasing temperature, gas particles gain sufficient energy to escape the solvent and solubility decreases.
