state boyle's law. why is it an inverse relationship?

Answer 1

Boyle's Law states that the product of volume and pressure in an ideal gas is a constant.

pV = constant.

If the pressure is increased, then in order to hold the product constant, then the volume must decrease. Hence it is referred to as an inverse relationship.

Answer 2

For a fixed mass of ideal gas at fixed temperature, the product of pressure and volume is a constant.

inverse, because for a fixed amount of gas, if you increase the pressure you will decrease the volume and vice versa.
