Steam is water vapour, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization.

Sensible, latent and total heat in evaporated water - steam - at different gauge pressures and boiling temperatures. Properties of Saturated Steam - SI Units Sizing steam pipes vs. pressure and velocity

Mar 18, 2025 · steam, odourless, invisible gas consisting of vaporized water. It is usually interspersed with minute droplets of water, which gives it a white, cloudy appearance. In nature, steam is produced by the heating of underground water by volcanic processes and is emitted from hot springs, geysers, fumaroles, and certain types of volcanoes.

Apr 12, 2010 · Steam is just water in the form of gas (vaporized). In its most natural and purest state (without the addition of condensed water), it is a colorless or an invisible (transparent) gas; but ordinarily, most people identify it as the gas coming out from boiling water which seems to be colored white and is somewhat visible to the naked eye.

If saturated steam does not contain any water, it is known as dry and saturated steam. It contains just sufficient heat energy to maintain all the water in a gaseous state. If saturated steam contains liquid particles, it is known as wet steam. It does not contains sufficient heat energy to maintain all water in a gaseous state.

Steam is the gas formed when water passes from the liquid to the gaseous state. At the molecular level, this is when H2O molecules manage to break free from the bonds (i.e. hydrogen bonds) keeping them together.

Nov 1, 2024 · Steam is the gas formed when water passes from a liquid to a gaseous state, often as a result of evaporation or boiling. This occurs when water is heated and the bonds connecting its molecules break more rapidly than they can form, allowing some molecules to break free and form an invisible gas.

May 22, 2019 · Steam is an invisible gas consisting of vaporized water, which is formed when water boils. When steam is visible, it contains the visible mist of water droplets. Such steam is referred to as “ wet steam “, but “ dry steam ” is always invisible.

Steam is the gaseous phase of water which is formed when the necessary latent heat of vaporization is supplied to water at its boiling point. Steam is created in power plants at high pressures by the burning of a fuel within a boiler.
