Question
Chapter 9, Problem 2SC
Interpretation Introduction
Interpretation:
The reason for the paraphrasing of the two laws of
Concept Introduction:
The first law of thermodynamics is that the energy can neither be created nor destroyed, but can be transformed from one form to another.
The second law of thermodynamics is that the total entropy of the system is always increasing over time as entropy can never be negative.
