Boyle’s law states that, as the pressure of a gas increases, the volume decreases true or false?

True.

Boyle's law was given by Robert Boyle in 1662.

Boyle's law was given for gases, this law states that the pressure (p) and volume (v) of a gas are inversely related to each other at constant temperature. Which means if the volume of the gas increases, then pressure decreases and vice versa, at constant temperature.

                          p ∝ 1/v .

Result: The given statement is true.
