A metal radiator is made from 10.36 kg of iron. The specific heat of iron is 0.449 J/g °C. How much heat, in kJ, must be supplied to the radiator to raise its temperature from 25.0 °C to 55.0 °C.

The specific heat capacity of iron is 0.449 J/(g middot degree C) How much heat must be supplied to a 26.0 kg radiator to raise its temperature from 25.0 degree C to 55.0 degree C? A piece of iron is heated to 99.5 degree C in boiling water, then dropped in a coffee cup calorimeter containing 75.0 g of water at 21.7 degree C. The final temperature of the system is 23.7 degree C. What was the mass of the piece of iron? A 0.235 g sample of an experimental fuel is burned in a bomb calorimeter that has been calibrated to have = 118 J/degree C, and the temperature increases by 5.19 degree C. Calculate the energy density of the fuel (energy per gram). Calculate the enthalpy change when 14.3 moles of water is vaporized at 100 degree C.
