What is the other name for solid carbon dioxide?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Dry ice.
Solid carbon dioxide is commonly known as dry ice. It is called dry ice because, unlike regular ice, it does not melt into a liquid form but sublimates directly into carbon dioxide gas at temperatures above −78.5°C (−109.3°F). Dry ice is used for cooling purposes, in theatrical effects to create fog, and in various industrial applications due to its ability to maintain very low temperatures without leaving any residue.
