If the balloon is filled with helium gas, there is no change in temperature and the amount of gas, the pressure stays the same.

Helium gas in a balloon is one example of gas pressure in a closed space that we can find around us. The application of gas pressure in a closed space is the relationship between air pressure and volume.

The relationship between volume and air pressure is the basis of Boyle's Law which was discovered by Robert Boyle in 1662. The fact that air pressure is inversely proportional to volume means that the higher the air pressure, the lower the volume of a container.

Conversely, if the lower air pressure is, the volume of the container or space will be larger.

Boyle's law equation is PV = Constant or P1V1 = P2V2.

P1 is the initial air pressure
V1 is the initial air volume
P2 is the final air pressure
V2 is the final air volume.
