Solution

The correct option is C
Charles' law

Charles' law states that the volume of a fixed mass of a gas increases or decreases by 1/273.15 of its volume at 0^oC for each degree rise or fall in temperature, if pressure is kept constant.

Q. The volume of a gas is directly proportional to its absolute temperature and inversely proportional to pressure on it. When volume is 140 ml the absolute temperature is 280°K and the pressure on it is 15 mm. If the absolute temperature is 300°K, the pressure on it is 20 mm. Find the difference in its volume.
