Water is used as a coolant in motor car radiators because:
- The specific heat capacity of water is very high.
- This means to increase the temperature of water even by a degree celsius, requires very high amounts of heat.
- Motor car radiators get heated up very quickly.
- It is essential to keep the radiators cool to prevent accidents.
- Water is used for this purpose because water can absorb this heat without any increase in its own temperature.
