Thermodynamics Question 10
Question: The slopes of isothermal and adiabatic curves are related as
[CPMT 1971; BHU 1996; MH CET 1999; UPSEAT 2000; RPET 2003]
Options:
A) For an isothermal change PV = constant
B) In an isothermal process the change in internal energy must be equal to the work done
C) For an adiabatic change $ \frac{P _{2}}{P _{1}}={{( \frac{V _{2}}{V _{1}} )}^{\gamma }} $ , where $ \gamma $ is the ratio of specific heats
D) In an adiabatic process work done must be equal to the heat entering the system
Show Answer
Answer:
Correct Answer: A
Solution:
Since $ PV=RT $ and $ T= $ constant;
$ \therefore \ PV= $ constant.
