Why does adding Antifreeze to car radiator increase the boiling point of the water in the radiator?

Adding antifreeze to a car radiator increases the boiling point of the water because it creates a solution that raises the liquid's boiling point through a phenomenon known as boiling point elevation. This occurs because the antifreeze, typically composed of ethylene glycol or propylene glycol, disrupts the formation of vapor pressure, requiring higher temperatures for the solution to boil. Consequently, this allows the engine to operate at higher temperatures without overheating, improving performance and efficiency.
