Question

The solubility of gases in water ________ with the rise in temperature.

• A. increases
• B. decreases
• C. decrease then increases
• D. none of these

Answer 1

The correct option is B decreases

Increased temperature causes an increase in kinetic energy of the molecules.

The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution.

Thus an increase in temperature will decrease the solubility of gases in water.

Thus, option B is correct.
