How does the solubility of a gas change with increasing temperature? A. It increases. B. It decreases. C. It is uniform. D. The temperature does not affect the solubility of a gas.

The correct answer is option B.

Explanation:

The solubility of gas decrease with increase in temperature.

This is because when temperature increases the kinetic energy of the gas particles present in the solution also increases due to which gas particles starts moving faster.

Faster the speed of the particles in solution more easily they can escape from the solution resulting in decrease in solubility of gas in solution.

Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break inter molecular bonds and escape from solution.
