Mini Engine Replacement Mini Metal & Cold Cylinder Piston

Description: A engine is a heat engine that operated by cyclic compression and expansion of air or other gas at different temperatures, such that there will conversion of heat energy to mechanical work. Hot motor model physics teaching aids educational toys Burnning the alcohol lamp for a while, the expansion of air will work as to run the pistons and flywheel, then the expanding be cooled in cold chamber. As this process will be repeatedly circulating, the flywheel will continuously work. The hotter the tube gets, the faster the flywheel go Very interesting! Great for cultivating students' interest in physics, more intuitive and easy to understand how heat engergy is converted into mechanical work.
