Generally, the expansion of water into steam depends greatly on temperature and atmospheric pressure. When water boils and turns from a liquid into a gas, the gaseous form fills a much larger area. Steam has been an important tool in years of human invention and has been used to power engines or cook food like vegetables or rice. It is most often used to remove wrinkles from clothing.
