Explain problem in word or pdf format
Closed path with 4 processes
1st process Isochoric
V= 2m^3
P-initial = 3x10^4 Pa
P-final = 8x10^4 Pa
2nd process Isobaric
V-initial = 2m^3
V-final= 5m^3
P = 8x10^4
3rd process Isochoric
V= 5m^3
Pi =8x10^4 Pa
Pf =3x10^4 Pa
4th process Isobaric
Vi = 5m^3
Vf= 2m^3
P= 3x10^4 Pa
a) Process 1 requires 600 joules added, process 2 requires 200 J added. What is the change in internal energy as a result of the first two processes?
b) Total amount work done in complete cycle of four processes?
