คุณลักษณะ

• When a piston is suddenly pushed into a cylinder (glass tube), the internal temperature rises rapidly due to adiabatic compression, and tissue paper or cotton placed in the cylinder ignites.
• The red flame can be clearly seen in the window at the bottom of the aluminum pipe, so the display effect is excellent.
• The experiment is mounted on a strong aluminum pipe, so anyone can easily do it without danger.
• Also, when a small amount of dry ice is put into the cylinder and the piston is pushed slowly, it can be observed that the dry ice liquefies.
• From that state, if you slowly remove the piston, it will turn into a white solid again, and if you leave it as it is, it will vaporize, so you can observe the three forms of matter.
