In an adiabatic thermodynamic process, which parameter remains strictly zero throughout?
Answer and explanation
Correct answer: B. Heat exchange dQ
- Step 1: An adiabatic process is one that occurs without heat exchange between system and environment. Step 2. By definition, dQ = 0, so dU = -dW. Answer: Heat exchange dQ. Why not the others: Work done is generally non-zero in adiabatic expansion; temperature change is zero in isothermal processes; pressure change is zero in isobaric processes.
