According to charles' law, the volume of a gas becomes zero at
Answer Details
Charles' law states that at a constant pressure, the volume of a gas is directly proportional to its temperature. As the temperature of the gas decreases, its volume also decreases. According to the law, the volume of a gas would theoretically become zero at a temperature of -273 oC (also known as absolute zero), at which point the gas would have no thermal energy left to contract or expand. Therefore, the correct option is: -273 oC.
