Explain, why do aquatic animals prefer to stay at lower level of water during summer?


Why do gases always tend to be less soluble in liquids as the temperature is raised?


The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of 20% is to 79% by volume at 298 K. The water is in equilibrium with air at a pressure of 10 atm. At 298 K if the Henry’s law constants for oxygen and nitrogen are 3.30 × 107 mm and 6.51 × 107 mm respectively, calculate the composition of these gases in water.

(A) He + O2

(B) Ne + O2

(C) Ar + O2

(D) Kr + O2
