Question

Aquatic species feel more comfortable in winter than in summer because -

• A. $\%$ of $O_2$ in air decreases in summer due to high temperature
• B. Atmospheric pressure decreases in summer leading to reduced solubility of gases in water
• C. Solubility of gases in water decreases as the temperature increases due to increased Henry’s constant
• D. Aquatic species feel skin burn due to increased temperature of the water.

Answer 1

The correct option is C Solubility of gases in water decreases as the temperature increases due to increased Henry’s constant

According Henry’s law of solubility of gases -
$P=K_{H}X$

With increase in temperature increases, thus ‘x’ decreases given the partial pressure of $O_2$ remains same.
