Conversation

Have you ever used a pycnometer for measuring density?

No, I haven't! What exactly is it used for?

It's a standard vessel that helps determine the density of liquids or solids.

That sounds really interesting! I might need to try it for my experiments.

Root Explanation

Pycnometer → It is formed from "pycnos" (from Greek πυκνός, meaning dense or thick) and "metron" (from Greek μέτρον, meaning measure). A pycnometer is an instrument used to measure the density of liquids or solids.

Memory Tip

Think of 'density' ('pycnos') being measured ('metron') — that's what a pycnometer does.
