Physics Question on Thermodynamics
A thermodynamic system is taken through the cycle abcda. The work done by the gas along the path bc is :
A
Zero
B
30 J
C
–90 J
D
–60 J
Answer
Zero
Explanation
Solution
Work done along bc is calculated using the formula W = P ∆V .
- Here, the volume remains constant along bc (∆V = 0).
- Therefore, W = 0.
