Question: A gas expands under constant pressure P from volume $ V _{1} $ to$ V _{2} $ . The work done by the gas is
[CBSE PMT 1990; RPMT 2003]
Options:
A) $ P(V _{2}-V _{1}) $
B) $ P(V _{1}-V _{2}) $
C) $ P(V _{1}^{\gamma }-V _{2}^{\gamma }) $
D) $ P\frac{V _{1}V _{2}}{V _{2}-V _{1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Work done $ =P\Delta V=P(V _{2}-V _{1}) $
