Dry ice colloquially means the solid form of carbon dioxide. It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects.

A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature (see ...
Thermite. A thermite mixture using iron (III) oxide. Thermite ( / ˈθɜːrmaɪt /) [1] is a pyrotechnic composition of metal powder and metal oxide. When ignited by heat or chemical reaction, thermite undergoes an exothermic reduction-oxidation (redox) reaction. Most varieties are not explosive, but can create brief bursts of heat and high ...
Arizona prohibits dry ice bombs if there is an intent to cause injury, death, or damage to the property of another, [13] as well as their possession by "prohibited possessors" such as convicted felons and illegal immigrants. [14] In Utah, simple possession of a dry ice bomb or similar pressurized chemical reaction bomb is a second-degree felony ...
Carbon dioxide is a chemical compound with the chemical formula CO 2.It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO 2 is the primary carbon source for life on Earth.
Ice is still used to cool and preserve food in portable coolers. [110] Ice cubes or crushed ice can be used to cool drinks. As the ice melts, it absorbs heat and keeps the drink near 0 °C (32 °F). [139] Ice can be used as part of an air conditioning system, using battery- or solar-powered fans to blow hot air over the
Coolant. A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical ...
