Question

Why is glycol and water mixture used in car radiators in cold countries?

Answer 1

Answer:

Water freezes at temperatures much less than 0 degree Celsius when ethylene glycol is added to it. It is used as an anti-freeze. This practice was mostly practiced in older radiators in cold weather conditions. ... Another aspect of using the glycols is that they have a higher boiling point(197 deg C) as compared to water.
