Antifreeze in a car's engine is an example of the application of freezing point depression.
Here's why:
1. Antifreeze is added to a car's engine coolant to lower the freezing point of the liquid. This prevents the coolant from freezing in cold temperatures, which could lead to engine damage.
2. Freezing point depression is a colligative property that occurs when a solute (in this case, the antifreeze) is added to a solvent (the engine coolant). The presence of the antifreeze lowers the freezing point of the coolant, making it effective in colder climates.
3. By lowering the freezing point of the coolant, the antifreeze helps maintain the proper functioning of the engine by preventing the coolant from solidifying in low temperatures.
In conclusion, antifreeze in a car's engine is a practical example of how freezing point depression is utilized to improve the performance and longevity of the vehicle.
