Question

An adiabatic reversible process is one in which:

• A. temperature of the system does not change
• B. the system is not closed to heat transfer
• C. there is no entropy change
• D. none of the above

Answer 1

The correct option is C there is no entropy change

During adiabatic process, there is no heat transferred between the system and the surrounding.
The entropy change of a system is the ratio of the amount of heat transferred in a reversible manner to temperature at which heat transfer occurs. When heat transferred is zero, the entropy change is zero.
