gas
word
Definition
A substance like air that is not solid or liquid, often used to mean fuel for cars (short for gasoline in American English) or the air-like form of any substance.
Usage & Nuances
'Gas' in American English often means 'gasoline' (fuel for cars), but in science or British English, it means a substance in a gaseous state (like oxygen, hydrogen). Don't confuse with 'petrol', the British word for car fuel. Also used in phrases: 'step on the gas' (go faster), 'gas bill' (payment for heating).
