A) \[q=\Delta E-W\]
B) \[\Delta E=q-W\]
C) \[\Delta E=q+W\]
D) \[\Delta E=q+pdV\]
Correct Answer: B
Solution :
Consider a system in a state A, having internal energy \[{{E}_{N}},\] q amount of heat is supplied to system so that the system attains the state B, having internal energy\[{{E}_{B}}\]. Let W is the work done by the system to attain this change, then from first law of thermodynamics. If\[\Delta E={{E}_{B}}-{{E}_{A}}\]then \[\Delta E=q-W\]You need to login to perform this action.
