Detailed explanation-1: -Dry ice has a surface temperature of-109.3 degrees Fahrenheit (-78.5 degrees Celsius).
Detailed explanation-2: -Dry Ice is particularly useful for freezing, and keeping things frozen because of its very cold temperature:-109.3°F or-78.5°C.
Detailed explanation-3: -The temperature of dry ice is around-80 C or 195 K (195 degrees above absolute zero). Oxygen, argon, and nitrogen freeze at around 65 K. Neon and hydrogen freeze at 10 to 20 K. Normal helium, as it turns out, doesn’t ever freeze exactly.
Detailed explanation-4: -Dry ice is the solid form of carbon dioxide (CO2). It’s called “dry ice” because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas.
Detailed explanation-5: -Dry ice is basically solidified carbon dioxide and is called so because the gas on solidifying gives an appearance similar to that of ice. Unlike ordinary ice, it does not melt into a liquid but changes directly into CO2gas, a phenomenon known as sublimation.
