Question

Which substance is used as coolant in radiator?​

Answer 1

Answer:

Ethylene glycol (antifreeze) is used in the cooling of a car radiator during the winter because it has a much lower freezing point than water. The specific heat of antifreeze (pure or mixed with water) is lower than that of pure water. But in the summer water in a car radiator serves as a coolant.
