Q. As 1.Temperature is directly proportional to pressure
2.Pressure is inversely proportional to Volume

But in summers, let us say at 45^oC if we fill air in tyres of bikes, as the temperature is high, pressure should be high and when pressure becomes high, volume should decrease!

But this does not happen!

Why?

Q. The pressure of a definite mass of a gas is directly proportional to the temperature and inversely proportional to the volume under the given conditions. If the temperature is increased by

40 %

and the volume is decreased by

20 %

then the new pressure will:

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.

Q. Volume is inversely proportional to pressure is:
