In a cyclic process, ΔU equals:
A0 (returns to initial state)
BQ
CΔS
DW
Answer & Solution
Correct answer: A. 0 (returns to initial state)
In a cyclic process, the system returns to its initial state. So ΔU = 0 (since U is a state function). Therefore Q = W (net heat absorbed = net work done by system).
