Chem help! Heat transfer to wather?

• In a water-cooled engine, running under constant conditions, 15.6 kJ of heat energy is transferred from the engine to the water coolant every second. If the water is flowing at a rate of 14.7 L/min, in a closed circuit between the engine and the radiator, by what amount must the temperature of the water be reduced by the radiator before it returns to the engine? Assume that the density of water is 1.00 g/cm3 and the molar heat capacity of water is 75.4 J/mol/K. (Give your answer to the nearest 1 degC or 1 K.) Note: The Specific Heat of a substance is the amount of heat energy required to raise the temperature of 1 g of the substance by 1 K. The specific heat of liquid water is about 1 calorie or 4.18 Joules

• Answer:

  First convert 14.7 L/min into grams per second. Heat flux/water mass flow rate = energy per gram from which you can get the temperature rise. THe temperature must fall by the same amount or the radiator will boil over.
