How does an increase in pressure affect the volume of a confined gas?

The relationship between the pressure and volume of a fixed amount of gas at a constant temperature is described with the Boyle's Law:

"For a fixed mass of gas, at a constant temperature, the product (pressure x volume) is a constant."

Pressure x Volume = constant

According to this, the absolute pressure and volume of a given mass of confined gas are inversely proportional, provided the temperature remains unchanged within a closed system. So, if the pressure is increased than the volume will be decreased.

The relationship between the pressure applied to a gas and the volume of the gas is inverse. An increase in pressure reduces the volume of the gas.
