10.Boyle's law states that: (A)Equal amounts of gases occupy the same volume at constant temperature and pressure. (B) The volume of a fixed amount of gas is inversely proportional to its pressure at constant temperature. (C) The volume of a fixed amount of gas is directly proportional to its temperature in Kelvin at constant pressure. (D)The total pressure of a mixture of gases is the simple sum of the partial pressure of all of the gaseous compounds.
