A) \[\Delta E=\Delta W\ne 0,\,q=0\]
B) \[\Delta E=W=0,\,q\ne 0\]
C) \[\Delta E=0,\,W=q\ne 0\]
D) \[W=0,\,\Delta W=q\ne 0\]
Correct Answer: A
Solution :
In closed insulated container a liquid is stirred with a paddle to increase the temperature, therefore it behaves as adiabatic process, so, for it \[q=0\]. |
Hence, from first law of thermodynamics |
\[\Delta E=q+W\,if\,\,q=0\] |
\[\therefore \] \[\Delta E=W\,\] but not equal to zero. |
