Answer:
W=0.217kJ
Explanation:
#Boundary Work is energy expended when a force acts through a displacement
The boundary of work can be calculated as the area under the P-V curve for all the 4 stages measured:
[tex]W= \sum_{n=1}^{5} \frac{P_{n+1}+P_{n+2}+P_{n+3}+P_{n+4}+P_{n+5}}{2}\\\\=0.5((290+300)(1.1-1)+(270+290)(1.2-1.1)+(250+270)(1.4-1.3)+(220+250)(1.7-1.4)+(200+220)(2-1.7))\times 10^-^3kJ\\\\=0.217kJ[/tex]
Hence the boundary of work done by a gas during this 4-stage process is 0.217kJ
