If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cycle process, then
Text Solution
Verified by ExpertsThe correct answer is:
C
In a cyclic process, system is not isolated from the surroundings. In a cyclic process, a system
starts from one point and ends at the same point. in this case, the change in the internal energy must again be zero and therefore the thermal energy added to the system must equal the work done during the cycle. That is, in a cyclic process.
Δ U = 0 or E = 0
