प्रश्न
A liquid X has specific heat capacity higher than the liquid Y. Which liquid is useful as coolant in car radiators.

उत्तर
The specific heat capacity of liquid X is higher than that of Y. So, for same mass and same heat energy, the rise in temperature for X will be less than that of Y. As a coolant in car radiators, the liquid needs to absorb more energy without much change in temperature. So, liquid X is ideal for this function.
