A 1.3 kg block of iron at 29 °C is rapidly heated by a torch such that 15 kJ is transferred to it. What temperature would the block of iron reach (assuming the complete transfer of heat and no loss to the surroundings)? If that same amount of heat (15 kJ ) was quickly transferred to a 810 g pellet of copper at 32 °C, what temperature would the copper reach before it begins losing heat to the surroundings? Use the equation for heat capacity and the following heat capacity values: mc,AT 0.450 J/(g . °C) 0.385 J/(g- °C) C, Fe(s) C Cu(s) Express the final temperatures of the iron and copper in °C to two significant figures separated by a comma.

What mass of carbon monoxide must be burned to produce 175 kJ of heat under standard state conditions?
9.100 Two baking sheets are made of different metals. You purchase both and bake a dozen cookies on each sheet at the same time in your oven. You observe that after 9 minutes, the cookies on one sheet are slightly burned on the bottom, whereas those on the other sheet are fine. (You are curious and you vary the conditions so you know the result is not caused by the oven.) (a) How can you use this observation to infer something about the specific heat of the materials in the baking sheets? (b) What is themathematical reasoning (equation) that you need to support your conclusion?
The temperature of the cooling water as it leaves the hot engine of an automobile is 240 F. After it passes through the radiator it has a temperature of 175 F. Calculate the amount of heat transferred from the engine to the surroundings by one gallon of water with a specific heat of 4.184 J/g oC.
