An ideal gas is taken from point A to the point B as shown in P-V diagram keeping temperature constant. The work done in the process is –
A
(PA – PB) (VB – VA)
B
21 (PB – PA) (VB + VA)
C
21 (PB – PA) (VB – VA)
D
21 (PB + PA) (VB – VA)
Answer
21 (PB + PA) (VB – VA)
Explanation
Solution
WAB = + Area of trapezium
= + 21 [PB+PA][VB−VA]
