An experimental device for a Charles law is provided to improve a learning ability of a user by inducing an interest of science through a real experiment. An experimental device for a Charles law includes a pipette(100), a pigment object, a cork(200) and a transparent hose(300). A small diameter tube(120) is formed on an end of the pipette(100). A large diameter tube(110) which is extended to be coupled to the small diameter tube(120) is formed to have a larger diameter on the other end of the pipette(100). The pigment object is injected into the small diameter tube(120) of the pipette(100) and is charged. The cork(200) is installed to close the large diameter tube(110) on an end of the large diameter tube(110) of the pipette(100). The transparent hose(300) is inserted and fixed into the small diameter tube(120) of the pipette(100). |
