Example

The scientist used an osmometer to determine the osmotic pressure of the solution.

Conversation

Have you ever used an osmometer in a science experiment?

No, I haven't, but I've heard it's really useful for measuring pressure.

Yeah, it can give you some interesting data about solutions.

I should look into that for my next project!

Root Explanation

Osmometer → It is formed from "osmo-" (from Greek "osmos", meaning push or impulse) and "-meter" (from Greek "metron", meaning measure). An osmometer is an instrument that measures the osmotic pressure or the tendency of a solvent to move through a semipermeable membrane.

Memory Tip

Think of 'osmosis' as a 'push' or 'impulse' to remember that an osmometer measures the pressure related to this movement.
