All processes for which the temperature stays constant are described by Boyle's law.
Boyle's law is expressed as p1 * V1 = p2 * V2, where p1 and V1 are starting pressure and volume, respectively. The ultimate values of these gas parameters are p2 and V2.
Boyle's law formula can be stated in a variety of ways, depending on the parameter we want to estimate. Let's imagine we wish to determine the pressure that results from changing a gas' volume under isothermal conditions. The Boyle's law equation thus reads: p2 = p1 * V1 / V2 or p2 / p1 = V1 / V2.
As we can see, the final-to-initial pressure ratio is the opposite of the volume ratio.

Hi there! All of the water returns to the atmosphere, it's called evapotranspiration and condenses. And then the water falls back to the Earth's surface and starts the cycle all over again. If you don't know what I mean, it's the Water Cycle.
