Root Explanation

Gas originates from the Greek word 'khaos' (meaning empty space or void) and was later adapted in the 17th century by the Flemish chemist Jan Baptist van Helmont, who coined the term to describe a state of matter that is neither solid nor liquid. The word reflects the concept of a substance that fills space.

Memory Tip

Think of the Greek word for 'void' or 'empty space' — that's why gas is a substance that fills up space around it.
