Question

Dry ice is the solid form of water.

• A. True
• B. False

Answer 1

The correct option is B False

• Dry ice is simply carbon dioxide that has been cooled and condensed.
• When it reaches room temperature and pressure, it is the melting process and expands directly into carbon dioxide gas.
• Dry ice is made by compressing and cooling gaseous CO₂ under high pressure, resulting in liquid CO₂.
• Dry ice is frequently used as a substitute for refrigeration for groceries and medical supplies due to its exceptionally low temperature of -78°C.

Therefore, the given statement is false.
