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.
Explanation of Solution
First law of thermodynamics:
Energy cannot be generated or destroyed. Energy can be adjusted from one form to another.
Second law of thermodynamics:
Energy tends to disperse or spread out. Thermal energy is always spontaneously moved from a cooler object to a hotter object.
Second law states that energy tends to disperse, or spread out and first law states that energy is conserved.
