State Henry's law. Why are aquatic species more comfortable in cold water as compared to warm water ?
Marking-scheme solution
•
At a constant temperature, the solubility of a gas in a liquid is directly proportional
to the partial pressure of the gas present above the surface of liquid or solution/
the partial pressure of the gas in vapour phase (p) is proportional to the mole
fraction of the gas (x) in the solution
•
Because the solubility of oxygen increases with decrease in temperature/ Because
of low solubility of O2 in warm water.
