Question

Dry Ice?

Answer 1

Answer: Carbon Dioxide

Explanation:

Dry ice is the solid form of carbon dioxide (CO₂). Unlike regular ice made from water, dry ice doesn't melt into a liquid when heated. Instead, it undergoes a fascinating process called sublimation, where it transforms directly from solid to gas at -78.5°C (-109.3°F).

The name "dry ice" comes from the fact that it appears to be ice but remains completely dry throughout the sublimation process. When dry ice sublimates, it produces a thick, white fog-like vapor that you've probably seen in theatrical performances, food preservation, or science experiments. This creates the dramatic smoky effect that makes it so popular for special occasions.

Dry ice has several important applications in our daily lives:

• Food preservation and shipping frozen items • Creating special effects in movies and stage performances • Cleaning processes in industries (dry ice blasting) • Scientific research and laboratory experiments • Medical transportation of vaccines and biological samples

It's important to handle dry ice with extreme care since it's much colder than regular ice and can cause frostbite if touched directly. The carbon dioxide gas it releases is also heavier than air, so proper ventilation is essential when using it indoors.
