(B) Cryoscopic constant is defined as the depression of freezing point of the solvent produced on dissolving one mole of a substance in 1000g of it. It is also called molal depression constant.
(C) Henry's law is a gas law which states that the amount of gas that is dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid when the temperature is kept constant.
