Temperature needed to boil water
WebAccording to WHO, temperatures of 140°F to 150°F are enough to kill most viruses, and boiling water makes it safe from pathogens like bacteria, viruses, and protozoa. Trivedi recommends a temperature of 160°F or greater when heating water or food products, to kill off bacteria like Legionella, a common bacteria found in water. WebWhat is the amount of energy (J or Wh) needed to boil one litre of tap-water in a regular kettle starting at room temperature (20°C)? The calculation itself assuming ideal and standard prerequisites would be interesting as well as factoring in the non-purity of tap-water and a typical kettle performance factor. physical-chemistry water heat Share
