Respuesta :
After a while at room temperature, a piece of dry ice, or solid CO2, vanishes without leaving a puddle of liquid behind.
What is solid CO2?
Dry ice, which is a solid form of carbon dioxide, is available. When used for short-term refrigeration, CO2 is usually used because it frequently sublimates from the solid form to the gas state due to the fact that it does not have a liquid state at normal atmospheric pressure. Carbon dioxide that is solid is known as "dry ice." Due to its ice-like appearance and the fact that it truly sublimes rather than melting, dry ice appears to be made of ice. Because the solid does not first become a liquid when heated, it is known as dry ice.
What is solid CO2 used for?
Dry ice, also known as solid carbon dioxide, is very cold (109 °F / 78 °C), and it is frequently used to cool vaccines, chill and freeze food, preserve blood and tissue samples, heat-treat metals, and even produce special effects like fog for events or stage plays. Because solid CO2 does not melt into a liquid when heated but instead transforms instantly into gas, it is referred to as dry ice. Sublimation is the name of this procedure.
