sublimation

Definition

Sublimation is when a solid turns into a gas without melting first. This happens when the solid absorbs enough energy to break the bonds between its molecules, but not enough energy to melt the solid.

One example of sublimation is when dry ice (solid carbon dioxide) turns into a gas. Dry ice is cold, so it doesn't need much energy to sublimate. When dry ice sublimates, it turns into a gas that looks like fog.

Another example of sublimation is when mothballs sublimate. Mothballs are made of a substance called naphthalene, which sublimates at room temperature. This is why mothballs can be used to keep moths away from clothes and other belongings.

How can the word be used?

Dry ice sublimates into carbon dioxide gas.

Etymology

The word "sublimation" comes from the Latin word "sublimare", which means "to raise up" or "to elevate". It was first used in English in the 17th century.

The word "to sublimate" means to change from a solid to a gas without going through the liquid state. It can also mean to change from one form to another without passing through an intermediate form.
