Question: In a closed insulated container, a liquid is stirred with a paddle to increase its temperature. In this process, which of the following is true [CBSE PMT 2002]
Options:
A) $ \Delta E=W=Q=0 $
B) $ \Delta E\ne 0,,Q=W=0 $
C) $ \Delta E=W\ne 0,,Q=0 $
D) $ \Delta E=Q\ne 0,,W=0 $
Show Answer
Answer:
Correct Answer: C
Solution:
As the system is closed and insulated no heat enter or leave the system, i.e. $ q=0 $ ;
$ \therefore \Delta E=Q+W=W $ .
