water in the gas phase, formed by the boiling of water
(Redirected from Steaming)

Steam is the name given to water when it is in a gas form. Steam is sometimes thought of as a cloud of translucent mist, however that is only the result of the steam condensing in the air, forming water vapor. Actual hot steam is invisible.

When the pressure of the atmosphere is 1013 mbar (this is about the average pressure for a place which is at sea level), water will boil (turn into steam) at 100 degrees Celsius. This is the boiling point. Boiling happens in a boiler. 100 degrees Celsius is the same temperature as 212 degrees Fahrenheit, 80 degrees Réaumur and 373.15 Kelvin.

A major use of steam is to power steam engines. A steam engine is a heat engine that performs mechanical work using steam as its working fluid.

Heating food


Steam gets sometimes used for heating food. In a pressure cooker, some water turns into steam, and some steam gets released (or let out) thru a valve.

There are other ways to steam food.
