Question

While hanging out in Lab, you decide to conduct another calorimetry experiment, but this time, you want to do it on a bit larger scale. You place 3.8 kg of water in a large aluminum can that has a mass of 15 kg. You heat the water and can up to an initial temperature of 80◦ C, and then slowly add 400 g of ice that has an initial temperature of −10◦ C. You stir the ice and water until all of the ice melts, and the system comes to an equilibrium temperature of 32◦ C. You feel good about things until you realize that you did not cover the aluminum can and that some heat was lost to the environment during the experiment. Use the information provided to calculate the amount of heat that was lost to the environment.
