Answer:
(A) Q=0: True
(B) W=0: False
(C) The entropy change of the system is always zero: True
(D) The total entropy change of the system and the surroundings is always zero: True
(E) The temperature of the system does not change: False
Explanation:
(A)
The heat in the system and the surroundings is not transferred, therefore Q=0
(B)
In every thermodynamic process, work is required, otherwise, there will be no process.
(C)
Isentropic means that the entropy is always the same, it means that there is no change.
(D)
As the entropy of the system does not change, the entropy of its surroundings will not change.
(E)
In order to be isentropic, a process needs to have a change in pressure and temperature.
