The use of antifreeze in the automobile radiator is an important application of__________________?
Correct answer: C. colligative property
- A. constitutive property
- B. additive property
- C. colligative property
- D. intrinsic property
Explanation
Antifreeze lowers the freezing point and raises the boiling point of the radiator liquid because these effects depend on the number of dissolved particles, not their chemical identity. Such effects are called colligative properties. The likely mistake is choosing additive property, but an additive property depends on the total contribution of the substances rather than simply the number of particles.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
