has a high density
|
|
|
can absorb a lot of heat

Explanation:
Detailed explanation-1: -Water is used in car radiators as coolant because water becomes hot by gaining a large amount of heat due to its high specific heat capacity . High specific heat capacity means, water has to gain a great amount of heat to get hot as compared to other liquids .
Detailed explanation-2: -Since specific heat of water is very high, so less even amount of water takes more out of the radiator with a minimal increase in its temperature. Thus water is used as coolant in radiator of car engine.
