We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature.
Boyle's law
This law states that the volume of a fixed mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
Why we wait a little
We wait a little after changing the volume of the trapped gas, to make sure that is the gas is back to room temperature because a change in temperature can alter the accuracy of the experiment.
