Thermodynamics Question 293
Question: A gas is expanded from volume $ V _{0} $ to $ 2V _{0} $ under three different processes. Process 1 is isobaric process, process 2 is isothermal and process is adiabatic. Let$ \Delta U _{1} $ , $ \Delta U _{2} $ and $ \Delta U _{3} $ be the change in internal energy of the gas is these three processes. Then-
Options:
A) $ \Delta U _{1}>\Delta U _{2}>\Delta U _{3} $
B) $ \Delta U _{1}<\Delta U _{2}<\Delta U _{3} $
C) $ \Delta U _{2}<\Delta U _{1}<\Delta U _{3} $
D) $ \Delta U _{2}<\Delta U _{3}<\Delta U _{1} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Since volume is same in all three process therefore temperature will be least having least pressure.
