WebGenerally, water boils at about 100°C (212°F). Under these conditions, the rate of evaporation can be as much as 1.5 cups (360 ml) every hour. This depends upon the degree of boiling that is achieved. If the liquid is boiled rapidly, then more energy is available to evaporate the water, resulting in a greater rate of evaporation. WebSep 12, 2024 · The answer has to do with boiling water. Go ask some people on the street about the boiling temperature of water.
