An apparatus for observing a phase change of material is provided to control duration about a triple state point of a dry ice by visually observing a phase change of the dry ice according to a change of temperature and pressure. An apparatus for observing a phase change includes a chamber(110), a pressure measuring device(120), a temperature measuring part(130), a regulator(140), and a controller(150). The chamber includes an inner loading space(112), a window, a cylindrical body, and a cap(115). The inner loading space loads a dry ice. The cap is coupled in the cylindrical body, and covers both openings of the cylindrical body. A screw line is formed in an outer surface of the cylindrical body. The window(115a) is positioned on a front of the cap. The cylindrical body and the cap are made of aluminum material. |
