The term energy is widely known and can refer to a variety of different concepts. In everyday language it most commonly refers to the physical or mental effort required to accomplish tasks, such as running a marathon or studying for an exam. For example someone may say: “I don’t have enough energy today, I think I need some coffee” or “I need to conserve my energy if I want to finish this project.”

The term enthalpy is much less familiar than energy and may be unfamiliar even in technical settings. It is used in chemistry and physics to describe the sum total of internal heat and pressure within a system (Basset, 2015). This can include gases, liquids, solids and other substances that are capable of holding heat inside them. For example one might say: “We determined the enthalpy of the reaction using thermodynamics principles”

Both terms are often used together when discussing systems related with heat such as heating systems found in buildings and other structures like homes and offices. People might ask questions like: “How efficient is your home heating system? Or more broadly: What type of heating system do you have installed in this building? Knowing how much energy is stored internally through measurements such as enthalpy allow people to better understand how various entities operate at both macroscopic level.

In conclusion, the terms energy and enthalpy are commonly employed together because they rely on each other when understanding thermodynamic processes within larger systems on both small scale and large scale operations (DeVoe et al., 2018). Knowing what amount of internal heat is stored within a substance allows us to predict its behavior under certain conditions based on measurements taken from its associated enthalpy value.
