Freezing temperature
WebThe freezing point of a solution is the temperature at which its vapor pressure is equal to that of pure water ice. Assuming ideal behavior (Raoult's law), the vapor pressure of a solution is: p=x w p 0, where x w is the molar fraction of water in the solution and p 0 is the vapor pressure of pure water. Freezing or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. There exist some scales defining several degrees of frost severity (from "slight" to "very severe") but they depend on location thus the usual temperatures occurring in winter.
