Question: When heat is given to a gas in an isothermal change, the result will be
[MP PET 1995; RPMT 1997]
Options:
A) External work done
B) Rise in temperature
C) Increase in internal energy
D) External work done and also rise in temp.
Show Answer
Answer:
Correct Answer: A
Solution:
In isothermal change, temperature remains constant, Hence DU = 0.
Also from $ \Delta Q=\Delta U+\Delta W $
Therefore $ \Delta Q=\Delta W $
