Chapter U5, Problem 4RE

Interpretation Introduction

Interpretation: The indication about energy by first and second law of thermodynamics needs to be described.

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.

Conclusion

Second law states that energy tends to disperse, or spread out and first law states that energy is conserved.
