Explanation:
Dry Ice is the common name for solid carbon dioxide (CO2). It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas (a process known as sublimation).

Explanation:
Solid carbon dioxide is known as dry ice. Because it looks like ice and because when it “melts” (it actually sublimes) it goes from solid straight to gas, no liquid, hence dry ice.
- Dry ice is the solid form of carbon dioxide.
- It is used primarily as a cooling agent.
- Dry ice sublimates at 194.65 K (−78.5 °C; −109.3 °F) at Earth atmospheric pressures.
- This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite).
