Ideal Gas Lab
Bouncing molecules, real physics: pressure emerges from wall collisions while P·V = n·R·T holds live.
This is real molecular dynamics — no faked pressure. Particles fly and bounce elastically off the walls, and the pressure is measured from the impulse they deliver to the walls (it matches the theoretical N·k_B·T/A). Heat the gas to speed the molecules, drag the piston to change the volume, add particles, and watch P·V = n·R·T stay balanced with R = 8.314 J/(mol·K).
