A cylinder contains a fixed mass of gas at 240 kPa. Its initial volume is 1.5 × 10-3 m3. At constant temperature, the pressure decreases to 90 kPa.

Use p1V1=p2V2p_1V_1=p_2V_2p1​V1​=p2​V2​ and 1 m3=1000 litres1\,\mathrm{m^3}=1000\,\mathrm{litres}1m3=1000litres.

What is the increase in volume, in litres?
