Steam

See also: Steam (service)

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.

Introduction

When the pressure of the atmosphere is 1013 mbar – average pressure for a place which is at sea level – water will boil to become steam at 100 °C. This is the boiling point. Boiling happens in a boiler. 100 °C is the same temperature as 212 °F, 80 °R and 373.15 Kelvin. Steam is mainly used for powering up steam engines. A steam engine is a heat engine performing 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.
