The process in which no heat enters or leave the system known as _____________?
Correct answer: C. adiabatic
- A. Isochoric
- B. Isobaric
- C. adiabatic
- D. Isothermal
Explanation
An adiabatic process has no heat transfer, so Q = 0 J, although the system's temperature may still change because work can be done. Isothermal is the likely mistake because it means constant temperature, not zero heat transfer.

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.
