There is no danger when putting dry ice in water. Because the temperature of dry ice is low, the water will freeze when it is put in the water. The dry ice will quickly absorb heat and convert it into carbon dioxide gas. It should be noted that dry ice will produce a large amount of carbon dioxide gas when placed in water, so make sure the water container is open and put the dry ice into the water in a ventilated environment. Dry ice (Dry Ice) is a kind of solid carbon dioxide. It is obtained by liquefying carbon dioxide into a colorless liquid under a pressure of 6250.5498kPa, and then solidifying rapidly under low pressure. Now dry ice has been widely used in many fields.
The history of dry ice can be traced back to 1823, when Faraday and Peter in the UK liquefied carbon dioxide for the first time. Later, in 1834, Chirolet in Germany successfully produced solid carbon dioxide. However, it was limited to research use at that time and was not widely used.
French chemist Thilorier was the first to document the emergence of solid dry ice. In 1835, he opened a cylinder containing a large amount of liquid carbon dioxide to observe it in its liquid form. A large amount of the water evaporates, leaving solid dry ice at the bottom of the container.
Over the next 60 years, dry ice was observed in various university laboratories but was not used for any practical applications. Even today, anyone can take a metal bottle containing liquid carbon dioxide (such as a CO2 fire extinguisher), open the valve, observe the gas cloud ejected, part of which will turn into dry ice snowflakes, and be very curious about it.
First time
In 1897, a British patent was granted to Herbert Samuel Elworthy, a doctor in the British Army Medical Corps. He needed to mix soda with whiskey, and liquid carbon dioxide worked well, but the metal bottles were too heavy for short trips. A 100-pound cylinder contains only 50 pounds of carbon dioxide. He prefers to make solid dry ice for soda. Unfortunately, dry ice didn't last long because it sublimated into a gas before it was all used. Since then, very little dry ice has been used for this patented purpose. Some doctors now use dry ice to remove warts.
Commercial
The first commercial application of dry ice in the United States was the first dry ice fire extinguisher manufactured by Perst Air Devices in New York State in 1923. Perst Air Devices produced solid dry ice for demonstration purposes. purpose, and in 1924 attempted to sell dry ice to railroad companies to replace water ice for cooling. Dry ice has twice the cooling capacity of water ice, making it much more efficient. Based on potential railroad business, a dry ice production plant was built in 1925. The successful Perst Air Devices was sold and the company was registered as the US DryIce Corporation under the trade name DryIce. Their attempt to use the dry ice brand again was challenged and rejected by the U.S. Supreme Court.
