Question

In cold countries, ethylene glycol is used in car radiators for both winter and summer seasons. Explain

Answer 1

Ethylene glycol is used in car radiators for both the winter and summer seasons because:

• It is used to cool the engine of the car.
• The temperature in the cold country remains constant in both summer and winter.
• Ethylene alcohol has a hydroxyl group in them which helps in increasing the freezing temperature and boiling temperature.
• It is mixed with water.
• In winter it increases its freezing point and in summers it increases the boiling point of water.
