Boyle's Law states that pressure and volume of a gas are inversely proportional (#P*V# is constant for constant mols of ideal gas and constant temperature).

As the piston is lowered to a new volume #1/2# the original, the volume the gas occupies decreases by that same factor, however, the particles are colliding with each other and the walls of the container more often, resulting in a greater pressure. The pressure increases by a factor of 2, and #P*V# is constant.
