Which of the following statements is incorrect? (Assume that pressure and amount of gas are constant.) A)Charles's law says that volume is directly proportional to temperature. B)If the absolute temperature of a gas doubles, then the volume of the gas will double. C)If the volume of a gas is halved, then the absolute temperature of the gas will be halved also. D)If the temperature of a gas sample decreases from 50^oC to 25^oC, the pressure will be halved. E)When a gas is cooled, the particles move more slowly.

Charles's law states that the volume of a gas is directly proportional to its temperature in kelvins, assuming pressure and amount of gas are constant. This means if the temperature doubles, the volume doubles (B is correct), and if the volume is halved, the temperature in kelvins is halved (C is correct, assuming the temperature is measured in kelvins). Statement A correctly summarizes Charles's law. Statement E is a general principle of gas behavior when cooled. Statement D is incorrect because it confuses Charles's law (which relates volume and temperature) with the effect on pressure, and it does not apply under the assumption of constant pressure.
