Question

Calculate the work done in Kilojoules gained by a system when a gas is compressed with a pressure of 310atm from 210L to 5.9L ?

Answer 1

Approximately `"6411 kJ"`

Explanation:

Work done on the gas at constant pressure is given as

`"W = -PΔV"`

`"W = -310 atm × (5.9 L - 210 L) = 63271 L atm"`

Convert `"L atm"` to `"kJ"`

`"W" = 63271 cancel("L atm") × "0.101325 kJ"/(1 cancel"L atm") ≈ "6411 kJ"`
