A sample of an ideal gas is taken through the cyclic process abca and shown in the figure. The change in the internal energy of the gas along the path ca is `-180J`. The gas absorbs 250J of heat along the path ab and 60 J along the path bc. the work done by the gas along the path abc is:

A

140 J

B

100 J

C

120 J

D

130 J

Text Solution

Verified by Experts

The correct Answer is:
D
`triangleu_(ca)= -180, triangleU_(ac)=180`
For abc
`-triangleQ= triangleU+w, 310=180+W`
`W= 130J`.
