At a constant temperature, the volume of a gas is
inversely proportional to its pressure.
Some gas has a pressure of 1.2 × 106 Pascals
and a volume of 2.3 x 10-8 m³.
a) What will the volume of the gas be when its
pressure is 5.2 × 104 Pascals?
b) Work out the pressure of the gas when its volume
is 4.2 x 10-⁹ m³.
