WebSeawater of 35 psu has a specific heat of 0.932 compared with 1.000 for pure water. Pure water freezes at 0 °C and boils at 100 °C (212 °F) under normal pressure conditions. When salt is added, the freezing point is lowered and the boiling point is raised. WebBecause the freezing point of pure water is 0°C, the sucrose solution freezes at –0.68°C. A similar property of solutions is boiling point elevation. A solution boils at a slightly higher temperature than the pure solvent. … WebThe boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 … finley wallpaper
