The relationship between pressure and volume, when moles and temperature of a gas are held constant, is: PV = k. We could say then, that:

If the volume of the gas is doubled, the pressure also doubles.

If the volume of a gas is halved, the pressure is doubled.

If the volume of gas is doubled, the pressure is unaffected.

If the volume of a gas is halved, the pressure is tripled.

PV = k

Solve for P

$P=\Large  \frac{k}{V}$

Look carefully at the equation for P. What happens if the volume increases (in other words: what happens if i increase the denominator of the fraction; will the result increases or decreases)?
