In thermodynamic terms boundary separates _?
Correct answer: C. System from surrounding
- A. Surrounding from the environment
- B. Reactants from contamination
- C. System from surrounding
- D. Products from the surrounding
Explanation
In thermodynamics, a boundary separates a system from its surroundings. A system is a collection of matter and energy that is under study. The surroundings are everything outside of the system.The boundary can be real or imaginary. A real boundary is a physical barrier that separates the system from its surroundings. An imaginary boundary is a conceptual barrier that separates the system from its surroundings.

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.
