Example

The scientists used aerogel to insulate the spacecraft due to its lightweight and thermal properties.

Conversation

Have you ever heard of aerogel?

Yeah, I read that it's super lightweight and really cool.

Right? It's fascinating how it's made from a gel but is mostly gas.

I know! I’d love to see what it looks like in person.

Root Explanation

Aerogel → It is formed from "aero-" (from Greek "aēr", meaning air) and "gel" (from Latin "gelare", meaning to freeze or congeal). The word "aerogel" refers to a gel that is derived from air, indicating its lightweight and porous nature.

Memory Tip

Imagine a gel that is made from 'air' ('aero-') and has a 'frozen' or solid-like quality ('gel'). This helps you remember that aerogel is a substance that is light and airy.
