Lab: Triple Point of Dry Ice

Lab: When three key substances of dry ice change three points, all three substance states (solid, liquid, gas) are generated. If all three of these problems exist simultaneously, it is very rare and interesting sight. Three points are defined as "Solid solids, temperature and pressure at which liquid and gas can coexist in equilibrium" (1). A good example of a substance that can achieve three focus is dry ice.

Dry ice is a solid of carbon dioxide (CO 2). It is called "dry ice" because it does not melt like wet ice. Instead, dry ice is converted to carbon dioxide. Because dry ice is very cold (-109 ° F / - 78.5 ° C), nontoxic and completely dry, it can be used to transport frozen foods and medicines or to consume consumable It is commonly used as a refrigerant. Another major application of dry ice is dry ice blast cleaning, effective and environmentally friendly cleaning method of industrial equipment.

Dry ice: Dry ice is the common name for solid carbon dioxide. The first term dry ice is a trademark of solid carbon dioxide manufactured by Perst Air Devices (1925), but now it refers to any solid carbon dioxide. Carbon dioxide is the natural component of air. Dry ice is safe for hood and laboratory experiments and provides care to avoid frostbite. Electromagnet: An electromagnet operates based on the principle that a current not only causes electrons to flow inside a circuit, but also a small magnetic field is generated. When winding a wire, the magnetic field becomes strong. Iron or steel objects surrounded by such coiled wires are also magnetized. This combination of electron energy, coil wiring and conductive metallic objects forms the basis of the device.
