Asked in Premeth Test 45 — Thermochemistry

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.
