evaporation
When water turns to steam, it is called evaporation. This occurs when water reaches its boiling point and changes from a liquid to a gas.
Water vapour (commonly referred to as steam) is turned back into liquid by a process of condensation. When the warm vapour touches a cold surface (a window pane, for instance) the vapour cools and forms droplets of liquid water.
The tree phases of a matter are called Solid, liquid and gas. For example, water is present in the form of Ice, liquid water and water-vapour or steam.
A condenser is the piece of equipment that changes steam and oil vapor to liquid. It works by cooling the vapor down until it reaches its dew point and condenses into a liquid form.
If the steam is transformed in a liquid this liquid can be evatporated again.
The process when water changes into a gas is called evaporation. Evaporation occurs for pure water at 100 degrees celsius (-173 K) when water molecules begin to move around very rapidly and split up.
steam or water vapour
Steam. Not to be confused with vapor, which is a suspension of liquid water molecules in another gas.
Gas is formed from evaporation when a liquid changes into a gas state at a temperature below its boiling point. Evaporation is the process by which molecules escape from the surface of a liquid into the air as vapor.
Water - water, ice and steam/vapour
when liquid is boiled it convert into steam and become vapour
Water can exist in three states: Solid, known as ice Liquid, known as water, and Gas, known as steam or water vapour. By the way, what we see as steam is in fact tiny droplets of water. Water vapour is transparent and colourless.
