Charles's law states that the volume of a gas sample varies directly with the absolute temperature, while keeping pressure and amount of gas constant. Therefore, option B is the correct statement of Charles's law. Option A is Boyle's law, option D is the inverse of Boyle's law, and options C and E are properties of the ideal gas law, but they do not describe Charles's law.
