Question

The temperature of 20kg water in the radiator of an engine of a car is 30°c. If the temperature of the water increases to 100°c after the engine is heated. What quantity of heat is absorbed by the water?​

Answer 1

Approximately 25 to 30 percent of the total heat input to the engine supplied by the fuel is absorbed by the engine cooling system. If this heat is not removed, engine internal temperatures would soon reach a point of component damage and engine failure.

• When it comes to the figures, most car engines have the maximum heat capacity of approximately 250 degrees Fahrenheit. That temperature actually represents liquid coolant since other components such as exhaust valves can go hotter than the given numbers.
