Question

 A gas undergoes two processes. In the first, the volume remains constant at 0.250 m³ and the pressure increases from 2.00 x 10⁵ Pa to 6.00 x 10⁵ Pa. The second process is a compression to a volume of 0.120 m³ 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.

Answer 1

1.

$A=∆pV=100~kJ,$

2.

$A=p∆V=65~kJ.$
