Definition

A measure of the total energy of a system, including its internal energy and the energy associated with its pressure and volume.

Example

In thermodynamics, enthalpy is used to calculate the heat transfer in processes at constant pressure.

Conversation

Have you ever heard about enthalpy in chemistry class?

Yeah, I remember it being related to energy and heat.

Right! It's basically the total energy of a system, including pressure and volume.

That makes sense! It's interesting how it all connects in thermodynamics.

Root Explanation

Enthalpy → It is formed from the Greek root "enthalpos" (meaning to put heat into) and the suffix "-y" (used to form nouns). The term 'enthalpy' refers to the total heat content of a system, indicating the heat energy that can be absorbed or released during a process.

Memory Tip

Think of 'putting heat into' a system, which helps you remember that 'enthalpy' is about the heat content of that system.
