Include freezing point temperatures for water
WebThe freezing point for water is 0°C or 273.15 Kelvin at atmospheric pressure. This means on cooling at 0°C water starts to transform into Ice from the liquid phase. What is the freezing point for pure water? For pure liquid water, it is incorrect to say that the freezing point is 0°C. WebWater’s heat of vaporization is around 540 cal/g at 100 °C, water's boiling point. Note that some molecules of water – ones that happen to have high kinetic energy – will escape …
