Physics is the study of the natural world around us - from the very large, such as the solar system, to the very small, such as the atom.

The study of physics is commonly divided into major topics such as General Physics, Thermal Physics, Light, Waves and Sound, Electricity and Magnetism. All these topics are related to two main ideas: matter and energy.

However, this blog will only cover thermal physics, which is chapter 7, 8, 9 of the textbook.
