A) \[\Delta E =Q-W\]
B) \[\Delta E =O+W\]
C) \[Q=W+\Delta E \]
D) \[W=Q+\Delta E \]
Correct Answer: B
Solution :According to the first law of thermodynamics, Energy can neither be created nor be destroyed. However, it can only be converted from one form to another'. Mathematically it is as follows: \[\Delta \Epsilon \]or \[\Delta U=q+W\] \[\Delta U=\] Change in internal energy q = Heat absorbed W = Work done Hence, the correct option is [b].
