(1) (a) Let’s derive an ideal gas law. Let’s start with a cubic box with side-length L. Now assume we have a particle traveling perfectly horizontally towards a single wall. When it collides with that wall, it will turn around and hit the wall on the other side. It will continue to bounce back and forth in this way forever. What is the period of this motion? In other words, how much time does it take for the particle to...
