Which thermodynamic process corresponds to a path on a PV diagram where no heat enters or leaves the system (Q = 0)?
Answer and explanation
Correct answer: A. Adiabatic process
- Step 1: An adiabatic process is one occurring without heat exchange with surroundings (Q = 0). Step 2. First law simplifies to delta U = -W. Answer: Adiabatic process. Why not the others: Isothermal has constant temperature (delta U = 0); isochoric has constant volume (W = 0); isobaric has constant pressure.
