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) \[W=0,\,\,\Delta E=q\ne 0\]
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\[q=0\] Then\[\Delta E=W\]
