Which term is another name for steam?

• A. Water vapour
• B. Boil
• C. Evaporation
• D. Steam

Answer: (D)

Water vapour is the scientific name for the gaseous form of water. Steam and water vapour refer to the same substance, but steam is the everyday term, especially for the hot gas produced when water boils. Since the question asks for another name for the gas form of water, the correct choice is water vapour. Boil describes the process of heating water to produce steam, not a name for the gas. Evaporation is another process by which liquid becomes gas at the surface, not a name for the gas itself.
