What is the value of heat energy (Q) in an adiabatic process?
Correct answer: B. 0
- A. 1
- B. 0
- C. -1
- D. 2
Explanation
In an adiabatic process, the value of heat energy (\(Q\)) is zero. This is because, by definition, an adiabatic process is one in which no heat is exchanged between the system and its surroundings, meaning the system is perfectly insulated. Therefore, \(Q = 0\) in an adiabatic process, and any changes in internal energy are due solely to work done by or on 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.
