Question

Which is the process in which no heat exchange is there between system and surroundings and in which no dissipative phenomena occur?

(a) Adiabatic process

(b) Reversible process

(c) Isentropic process

(d) Work

The question was posed to me in final exam.

My query is from A Brief Review of Thermodynamics topic in division Compressible Flow – Preliminary Aspects of Aerodynamics

Answer 1

Right answer is (c) Isentropic process

Explanation: A reversible process is one in which no dissipative phenomena occur. An adiabatic process is one in which no heat exchange is there between the system and the surroundings. A process that is both adiabatic and reversible is called an isentropic process.
