Thermodynamics Question 265
Question: Starting with the same initial conditions, an ideal gas expands from volume $ V _{1} $ to $ V _{2} $ in three different ways. The work done by the gas is $ W _{1} $ if the process is purely isothermal, $ W _{2} $ if purely isobaric and $ W _{3} $ if purely adiabatic. Then
Options:
A) $ W _{2}>W _{1}>W _{3} $
B) $ W _{2}>W _{3}>W _{1} $
C) $ W _{1}>W _{2}>W _{3} $
D) $ W _{1}>W _{3}>W _{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Work done is equal to area under the curve on PV diagram.
