1 HW 14 Tips; PHY 131 Sect. 10, 11, 15; Fall 2010 Prof. Pascuzzi Problem 1 “Adding Ice to Water” This is a basic calorimetry question which deals with testing your understanding of heat exchanges which occur when objects of different temperatures are in contact. Additionally, here, you are also faced with your understanding of heat exchanges during phase changes (i.e. when something melts/freezes or boils/condenses), which occur at constant temperature. Here, you are told a very cold ice cube is placed in a very warm glass of liquid water. The ice cube has an initial temperature that is well below 0° C, which of course is important to solving the problem. First, realize that there are three types of heat transferred to the ice before it and the water it is in come to thermal equilibrium; a) First, you must add heat to the ice to warm it to 0° C, which is done by using where is the change of temp from the original low ice temp to 0° C. b) Second, you must then add heat to the ice at 0° C to melt it (this is latent heat), which is done by using where is the latent heat of fusion of the ice. c) Lastly, you must then add heat to the ice water at 0° C to raise it to its final temperature, which is below the initial temperature of the warm water into which it was placed.
