Work = total area under the graph
= (4000 x 20) + 6000 x 20) + (½ x 6000 x 10) + (½ x 600 x 20)
= 80000 + 120000 + 30000 + 60000
= 290,000J

The figure below shows a master cylinder sealed at one end. Instead of brake fluid, the cylinder contains air.
When a force is applied to the piston, the length d changes from 6.0cm to 4.0cm. The pressure of the air increases but the temperature stays constant.
(i) Describe how the molecules of air exert a pressure.
(ii) Explain why the pressure increases even though the temperature stays constant.
(iii) The initial pressure of the air inside the cylinder is 1.0 x 105 pa. Calculate the final pressure of the air.
