1.	Why is water used in automobiles as a coolant?(a) It is not toxic for the environment(b) It has a high specific heat capacity(c) It has a high lubricating property which in turn keeps the engine cool by reducing friction(d) It is available in abundanceI have been asked this question by my school teacher while I was bunking the class.I would like to ask this question from Thermal Properties of Matter topic in section Thermal Properties of Matter of Physics – Class 11
Answer» CORRECT option is (b) It has a high specific HEAT capacity The best I can explain: Water has a high specific heat capacity because of which it can absorb LARGE amounts of heat before increasing its temperature. Hence, it is USED as a coolant.
