Explanation / Answer

13. There are 2 isentropic (adiabatic) and 2 iso thermal process in a Carnot cycle. All the process are reversible since it is an ideal cycle. The answer is (b)

14. (d). Except this all are ir-reversible

15. Since the entropy is not changing throughout, the process is reversible adiabatic. (c)

16. (a) Isentropic. Only reversible proces have maximum efficiency and hance minimum work.

17. Heat released by apple = m*Cp*delT = 0.18*3.65*17 = 11.2KJ (d)
