Definition

Referring to a state of a system that is not completely stable but lasts longer than other unstable states, often seen in chemistry or physics.

Example

The metastable state of the solution allowed it to remain in that form for a longer period than expected.

Conversation

I was reading about this chemical process that can be metastable under certain conditions.

That sounds interesting! What does it mean, exactly?

It means that it can remain in a state that's unstable but lasts longer than you'd expect.

Got it! So, it's like a temporary balance before things change.

Root Explanation

Metastable is formed from "meta-" (meaning beyond or change) and "stable" (from Latin "stabilis", meaning standing firm or stable). The term describes a state that is stable under certain conditions but can change under different circumstances.

Memory Tip

Think of 'meta-' meaning beyond or change, and 'stable' meaning firm. This helps you remember that 'metastable' refers to a state that is stable but can change under certain conditions.
