Question

___ is the change of solid-state directly to vapor state without going through the ___state.

• A. Sublimation
• B. liquid

Answer 1

Sublimation:

• The conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage is known as sublimation.
• An example of sublimation is dry ice which is a frozen form of Carbon dioxide
• A range of solids, including water, Iodine, Arsenic, and solid Carbon dioxide (dry ice), can sublimate at normal temperatures and pressures.
• Sometimes, some materials can also sublimate by creating conditions of low pressure.

Therefore, Sublimation is the change of solid-state directly to a vapour state without going through the liquid state.
