I have to write the procedure for a lab report that says, "You have recently been put on a technical service team to help your company's customers with your product line. One customer recently returned the coffee pot you manufacture, claiming that the temperature of the water is not hot enough to brew the coffee. Your team must measure the temperature of the water inside the pot. Unfortunately, the only thermometer you have available to you has no marks above 40 C. Using only this thermometer and other materials (coffeepot, thermometer, styrofoam cups, stirrers, graduated cylinders, balances, ice, cold water, samples of various metals).
I have started to write out the procedure which includes constructing a calorimeter and experimenting to find out how much heat is lost in the calorimeter. Beyond that, I have no clue. Could anybody help me out or at least give me some hints?
I'd be very grateful.
