The freezing point of ethanol is very low, i.e., -118° C. Thus, when a mixture of water and ethanol is cooled to a temperature of -50°C, it does not freeze. This mixture of water and alcohol is called anti-freeze and is used in radiators of motor cars in cold countries. It prevents water from freezing in radiators.
