Question

A coolant lowers the temperature in a steel engine weighing 16250 N and running at a temperature of 110°C. If the heat reduction in the engine was 10.3 MJ, what is the temperature of the engine reduced by? (12.7°C)

Step 1

The mass of the steel engine is,

Step 2

The formula for the heat required to change the temperature is,

Step 3

Calculate the change i...
