You can learn the essence of statistical thermodynamics. Through simulation of gas molecular motion, you can intuitively understand basic concepts such as molecular kinetic energy, temperature, and entropy. Prepare a hot gas and a cold gas separated by a wall. Remove the wall and mix the two gases. Then, place the wall, which is covered with Maxwell's demon, in the center of the container, again dividing the container in two. What will happen?
