No, dry ice is not hot; it is extremely cold.
Dry ice is the solid form of carbon dioxide (CO2). Its surface temperature is approximately -109.3°F (-78.5°C). Because of this extremely low temperature, direct contact with skin can cause frostbite. Therefore, it is crucial to handle dry ice with insulated gloves or tongs to avoid injury.
The reference material explicitly states that dry ice is "extremely cold" and that "direct skin contact with dry ice can easily cause frostbite." This reinforces the fact that dry ice is the opposite of hot.
Dry ice sublimes, meaning it transitions directly from a solid to a gas without passing through a liquid phase. This process absorbs heat from its surroundings, further contributing to its cooling effect.
