2.1 Ideal gases: A simple system to play with
Ideal gases are a natural place to start learning about thermodynamics. We have some intuition about how gases work and an "ideal" gas is t
Note 1. Introduction
1.1 What is thermodynamics?
Thermodynamics is a theory which gives us a set of relations between macroscopic properties we can measure (temperature, volume, pressure, length). Wha
