Question

What would be the primary reason that water is the main ingredient of the coolant used in your car’s radiator? 1. Water is colorless so you can see any rust easily 2. Water is an excellent solvent 3. Water has a high heat capacity 4. Water is non-flammable

Answer 1

option 3

Step-by-step explanation:

The correct answer is option 3.

Water is used as the main ingredient of coolant in car radiator because it has high heat capacity.

Specific heat capacity of a substance is the heat require to raise the temperature of the substance per unit mass.

Heat capacity of water is 4.184 J

As heat require to increase the temperature of the water of 1 gram is huge then water can absorb the heat of the radiator i.e. it can be used as Coolant.
