Vízforralási

Vízforralási refers to the process of boiling water. It is a common household and industrial activity primarily used for purifying water, cooking, and generating steam. The fundamental principle involves heating water to its boiling point, which is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.

The act of boiling water can effectively kill most microorganisms, including bacteria, viruses, and protozoa, making it a crucial method for water purification in situations where clean water sources are unavailable. This is particularly relevant in emergency preparedness, camping, and in regions with inadequate water treatment infrastructure.

In culinary applications, boiling is used for cooking a wide variety of foods, such as pasta, rice, vegetables, and eggs. It is also essential for making beverages like tea and coffee. Industrially, boiling water is a key component in power generation, where steam produced from boiling water drives turbines.

The equipment used for boiling water varies, ranging from simple stovetop kettles and pots to electric kettles, industrial boilers, and specialized laboratory equipment. The duration of boiling needed for effective purification can depend on the quality of the water and the specific contaminants it may contain, though a rolling boil for at least one minute is generally recommended.
