For this assignment, you will develop several models that show how light waves and mechanical waves
are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief
description of the interaction between the wave and the material. You will also compose two typewritten
paragraphs. The first will compare and contrast light waves interacting with different materials. The
second will explain why materials with certain properties are well suited for particular functions.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
