Question

What is an antifreeze?

Answer 1

1. An antifreeze is a substance that is added to a liquid (usually water) to lower its freezing point and prevent it from solidifying at low temperatures.
2. It is commonly used in the radiators of automobiles to prevent the engine coolant from freezing in cold climates.
3. A typical example is ethylene glycol, which, when mixed with water, depresses the freezing point of the mixture due to freezing point depression, a colligative property.
4. This ensures the fluid remains in the liquid state even below 0°C, allowing proper engine function and preventing damage from ice formation.
