Which of the following thermodynamic quantities are state functions: heat (q),work (w),enthalpy change (ΔH),and/or internal energy change (ΔU)?

Question

Quizplus · Accepted Answer

State functions are properties that depend only on the state of the system, not on how the system reached that state. Enthalpy change (ΔH) and internal energy change (ΔU) are state functions because they depend only on the initial and final states of the system. Heat (q) and work (w), however, are path-dependent and not state functions.
