Question

Why is it advised to add ethylene glycol to car radiator while driving in a hill station?

Answer 1

Adding ethylene glycol to car reduces the freezing point of water. It is used as an antifreeze in car rafiators during winters.

Hope it helps you.

Answer 2

Answer:

Ethylene glycol has a lower freezing point and hence acts as an antifreeze in automobiles.

Explanation:

• During the winter season the role of this mixture is to take heat from the radiator of the car.
• On mixing it with water (coolant) not only the absorption of heat from the engine becomes better but also the freezing point of the coolant increases hence the name antifreeze.
• In winters when normal coolant would freeze resulting in problem in automobiles this mixture would solve the problem.
