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 be a net conversion of heat energy to mechanical work. Hot air engine motor model kit physics teaching aids educational toys Burnning the alcohol lamp for a while , the expansion of air in the tube will work as a medium to run the pistons and wheel , then the expanding air will be cooled in cold chamber. As this process will be repeatedly circulating , the wheel will continuously work.The hotter the tube gets , the faster the wheel goes. Great for cultivating students' interest in physics , more intuitive and easy to understand how heat engergy is converted into mechanical work.
