Regular ice, in its solid form, is not considered wet. Wetness typically refers to the state of a substance when it is in contact with a liquid and has become moist or saturated with that liquid. Ice, composed of frozen water molecules, does not exhibit wetness because it is not in contact with a liquid. Rather, it is a solid state of water.
Dry ice, on the other hand, is the solid form of carbon dioxide (CO2) at a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). Unlike regular ice, dry ice does not melt into a liquid when heated; instead, it undergoes sublimation, transitioning directly from a solid to a gas. This is why it is called "dry" ice, as it does not produce a liquid phase during this process.
Dry ice is often used for cooling purposes, as it can reach extremely low temperatures. It is commonly employed in areas such as scientific research, food storage and transportation, and special effects for its ability to create a dense cloud of carbon dioxide gas when exposed to warmer conditions.
