In thermodynamics, what statement summarizes the First Law of Thermodynamics?
Answer and explanation
Correct answer: C. The change in internal energy equals heat added to the system minus work done by the system ()
- Step 1: In physics under the North Macedonian State Matura syllabus, The First Law expresses conservation of thermal and mechanical energy: . **Answer: The change in internal energy equals heat added to the system minus work done by the system (). Why not the others:** Entropy of an isolated system never decreases results from an incorrect physical formulation.
