There is no heat transfer into or out of a system during an) _____ process.
A) isothermal
B) adiabatic
C) isochoric
D) isobaric
E) There is always heat transfer during thermodynamic processes.

Question

Quizplus · Accepted Answer

An adiabatic process is one where no heat transfer occurs between the system and its surroundings, so the answer is B. The other processes listed (isothermal, isochoric, and isobaric) may involve heat transfer in or out of the system. The answer E is incorrect because there are certain thermodynamic processes that are adiabatic and therefore involve no heat transfer.
