Question

How is the Kinetic Theory related to the freezing point of water being reduced when salt is added to it?

Answer 1

Water normally freezes at 0˚C.But when an impurity like salt is added into it, water freezes at a comparatively lower temperature.Adding salt increases the number of molecules that are to be frozen.Thus it requires a much lower temperature to freeze the water.
