Question -


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

Options:
A .    % of O2 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: Option C
:
C

According Henry’s law of solubility of gases -
P  =  KHX
With increase in temperature increases, thus ‘x’ decreases given the partial pressure of O2 remains same.
