Steam

Steam is the gaseous phase of water that is formed when it boils. It is an important component in many industrial processes, including the generation of electricity and the sterilization of medical equipment.

Properties

Steam is invisible; the mist that we often associate with steam is actually tiny droplets of liquid water that have condensed from the steam. Steam is lighter than air and will rise. It is also a good conductor of heat and can cause severe burns.

Uses

Steam has many uses, including the following:

• Power generation: Steam is used to generate electricity in thermal power plants. The steam is used to turn a turbine, which is connected to a generator.

• Heating: Steam is used in heating systems to heat buildings and homes. It is also used in industrial processes that require heat.

• Sterilization: Steam is used to sterilize medical and dental equipment. The high temperature of the steam kills bacteria and other microorganisms.

• Cooking: Steam is used in cooking, especially in steaming vegetables and other foods.
