Question

What will happen to the ability of a gas to dissolve in a liquid if the temperature increases?

Solubility of the gas increases.
Solubility of the gas decreases.
Solubility of the gas increases or decreases.
Solubility of the gas is not affected.

Answer 1

B. The solubility of the gas decreases.

As the temperature of a liquid increases, the kinetic energy of its molecules also increases, which reduces the attractive forces between the molecules. As a result, the spaces between the molecules increase, and the solubility of the gas decreases.
