Question 16

A sealed air cushion used in protective packaging contains a fixed mass of gas. Its volume is 0.84 litres0.84\,\mathrm{litres}0.84litres when the pressure is 120 kPa. A package compresses the cushion, increasing the pressure by 60 kPa while the temperature remains constant.

Use p1V1=p2V2p_1V_1=p_2V_2p1​V1​=p2​V2​ and 1 litre=1000 cm31\,\mathrm{litre}=1000\,\mathrm{cm^3}1litre=1000cm3.

What is the volume of the gas after the cushion is compressed?
