Conversation

I've been reading about how isothermal processes work in physics.

Oh really? What does that mean exactly?

It's when something changes pressure or volume without changing temperature, pretty interesting right?

That does sound fascinating! I never knew temperature could stay constant like that.

Conversation

Have you ever heard of an isothermal?

Yeah, it's related to temperature, right?

Exactly! It describes a process where temperature remains constant.

Root Explanation

Isothermal → It is formed from "iso-" (meaning equal) and "thermos" (meaning heat). The word describes a condition where temperature remains equal or constant throughout a given area or system.

Memory Tip

Think of 'equal' ('iso-') temperatures — that's what isothermal means, a state where heat is constant.
