Q3
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.
