A gas undergoes two processes. in the first, the volume remains constant at 0.200 m' and the pressure increases from 2.00 x 10⁵ pa to 5.00 x10⁵ pa. the second process is a compression to a volume of 0.120 m? at a constant pressure of 5.00 x 105 pa.

(a) in a pv-diagram, show both processes.
(b) find the total work done by the gas during both processes.
