An adiabatic change is the one in which:
Correct answer: A. No heat is added to or taken out of a system
- A. No heat is added to or taken out of a system
- B. No change of temperature takes place
- C. Boyle's law is applicable
- D. Pressure and volume remain constant
Explanation
An adiabatic process is defined as a process in which no heat transfer takes place. This does not mean that the temperature is constant, but rather that no heat is transferred into or out from the system.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
