Question

Solubility of a gas in a liquid ____ with rise of temperature.

Answer 1

• As the temperature increases the kinetic energy of the substance increases.
• Kinetic energy: It is the amount of energy that a substance owns because of its motion.
• Therefore, with the rise in temperature, the kinetic energy of molecules of gas will also increase.
• Kinetic energy increases mean the movement of molecules of gas will increase.
• Due to which it becomes difficult to handle the fast-moving gas molecules, and the solubility of gas decreases.

Thus, the solubility of a gas in a liquid decreases with rise of temperature.
