Question

16. The process in which a solid directly changes into a gas.

Answer 1

Sublimation: Sublimation refers to the transit, change, or conversion of substances when they transition from one state to another, for as from a solid to a gas.

• Sublimation is the process in which a solid is converted into gas.
• For example - Dry ice, a frozen form of carbon dioxide, is the greatest illustration of sublimation. When dry ice is exposed to air, it immediately transforms from a solid to a gaseous state, which appears as fog. The gaseous state of frozen carbon dioxide is more stable than the solid-state.
