Interpretation: The indication about energy by first and second law of
Concept introduction: Energy combined with fires has many uses like heating home, cooking food, and moving cars.
Answer to Problem 4RE
First law of thermodynamics:
Energy cannot be generated or destroyed.
Second law of thermodynamics:
Energy tends to disperse or spread out.
