Definition

A substance that is used to create very low temperatures, often in a liquid form, like liquid nitrogen.

Example

Scientists use a cryogen to keep their samples at extremely low temperatures during experiments.

Conversation

Have you ever heard of cryogen used in science experiments?

Yeah, I read that it's used to achieve super low temperatures.

Exactly! I think they use it for preserving biological samples too.

That makes sense — it's cool how science uses cryogen for so many things!

Root Explanation

Cryogen → It is formed from "cryo-" (from Greek "kryos", meaning cold or frost) and "-gen" (from Greek "genes", meaning born of or produced by). The word "cryogen" refers to a substance that produces low temperatures or is used to create cold.

Memory Tip

Think of 'cold' ('cryo-') being 'produced' ('-gen') — that's why a cryogen is something that creates cold.
