REal World Application
Antifreeze is the perfect example of colligative properties in action. Antifreeze is a mixture of water and ethylene glycol. The ethylene glycol is the solute. Cars typically have water in their engines to keep them cool, but if the weather outside gets below freezing, the water would freeze, expand, and crack the engine. By using antifreeze, the freezing point is lowered and the cars are able to withstand a lower outside temperature before the engines are ruined.
