What is Henery'sLaw?

Question: What is Henery'sLaw?

Answer: According to this law solubility of a gas is directly proportional to the partial pressure of the gas.Solubility of a gas is represented by its mole fraction in the solution.
Mathematically  P = Kh  X 
where P = partial pressure of gas
Kh = Henery's constant
X = mole fraction of gas
As it is clear from above relationship
X is inversly proportional to Kh
And Kh is found to be decreased by increasing temperature so solubility decreases by increasing temperature.That is why aquatic life is more comfortable in cold water than in hot water.
