Answer 1

why ethylene glycol is used as a antifreezing agent in cars?

Because it has a much lower freezing point than water.

• Its role in an automobile is to absorb heat from the engine. When the temperature of the coolant increases to its boiling point, the system boils over.

Answer 2

Answer: Because the presence of impurities decreases the freezing point of water. Here ethylene glycol acts as an impurity. Thus the water freezes at a temperature lower than 0°C.

Hope this helps.
