Definition

A measure of how easily a substance spreads out or moves through another substance, often used in the context of heat or particles passing through a material.

Example

The diffusivity of the material determines how quickly heat can escape from the surface.

Conversation

I was reading about diffusivity in my science book today.

Oh really? That sounds interesting! What did it say?

It mentioned how diffusivity affects how heat moves through materials.

That makes sense! It’s cool how science explains everyday things.

Root Explanation

Diffusivity → It is formed from "dis-" (meaning apart) and "fundere" (meaning to pour). The word describes the quality of being able to spread or pour out in different directions.

Memory Tip

Think of something that 'pours apart' — 'dis-' means apart, and 'fundere' means to pour. This helps you remember that diffusivity refers to the ability to spread out.
