Answer:
Workdone during the process = 130kJ
Explanation:
Workdone by an expanding gas which is also called pressure-volume work, is defined as the pressure exerted by the gas molecules on the walls of the containing vessel. If work done by an expanding gas is the energy transferred to its surroundings i.e If volume increases, workdone is negative(loses energy).
In an isothermal process(constant Temperature of 300K, we use boyles law:
P1V1 = P2V2
V2 = (150 * 0.2)/800
= 0.0375 m3
W = -P(V2 - V1)
= 800*(0.0375 - 0.200)
= 130kJ
