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.

Pre Lab for Calorimetry Introduction Calorimetry is used to determine the specific heats and heat of transformation of materials. One can carry this out in one of two ways. One way is to take a material and isolate it from the environment and then put it a know power (energy per unit time) and measure how the temperature changes with time. When the material undergoes a phase transition (such as from ice to water) the temperature will stay constant until...

In a lab experiment involving calorimetry with brass and lead samples, a perfect calorimeter with no heat loss in which any heat lost from the metal was gained by the water was assumed. If the calorimeter was not perfect and some heat was lost to the environment, would this cause your calculated specific heat capacity of a solid (c) values to be higher or lower than the actual specific heat capacity of a solid (c) values?
