Etymology

Fugacity comes from the Latin root fug- and the verb fugere, which mean 'to flee' or 'escape', and you can see the same root in fugitive. In science, fugacity measures a gas's tendency to 'escape' from a container or change into a vapor, so the origin explains why it describes a gas trying to get away.
