A macroscopic property of a system which has some definite values for initial and final states, and which is independent of the path adopted to bring about a change is called:
Correct answer: B. State function
- A. State
- B. State function
- C. Surrounding
- D. System
Explanation
The macroscopic property of a system that has definite values for the initial and final states and is independent of the path taken to bring about a change is called a "state function" or a "state variable." State functions are properties of a system that depend only on its current state and not on the specific process or pathway by which the system reached that state. State functions are particularly useful in thermodynamics because they allow us to analyze and predict changes in a system's properties without needing to know the details of the intermediate steps or the specific process by which the change occurred. These properties are determined solely by the initial and final states of the system.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
