Subliming

Key Stage 3

Subliming is when a liquid turns into a gas.

Noun: Sublimation

Verb: To sublime

Only a few solids sublime.

Sublimation is a reversible process. When a solid sublimes into a gas you can deposit that gas back into a solid.

Heating a solid will cause it to sublime into a gas.

When you heat a solid:

The particles in the solid vibrate faster until they are moving fast enough that they break the bonds holding the particles together. The particles become free to move anywhere which makes the state a gas.
