This will be the calorimeter. Another modification was used for the third and fourth trial to determine the change in accuracy when using a conductive calorimeter. Due to various thermal properties of styrofoam, you may assume that experiment (MS Excel format): Enter TA password to view answers to questions from this Our calorimeter will absorb and lose heat. The precision of the temperature probe is given as You can also write the methods/procedure in numbered step format. The sample must be poured safely but quickly into the calorimeter, so that a minimal amount of heat is lost to the surrounding air. 0000000016 00000 n in Table 1 below. instrument called a calorimeter is used to measure specific heat. Specific Heat Capacity. University of Wisconsin, 2006. Get your own free piece of graphite to run this experiment. <<425D0D7D1060B34ABB8EBE65C0A09F8C>]>> For the purposes of this experiment, data was recorded at every 30 second interval. accurate. times if you do not think through the steps ahead of time. Figure 6: Graph displaying the relationship between Temperature (C) and Time (minutes) during the second trial using a Styrofoam cup, tongs held the sample while heated. The time that the peak temperature occurred is displayed noticeably in the graphs of the experimental data. Dr. Gustafsson was awarded the ITCC Thermal Conductivity Award at the 27th International Thermal Conductivity Conference in 2003. q = 209 q = (4)(50g)(1 C) q = 313 q = (4)(50g)(1C), s = -209 (1)(22C 100C) s = -313 (4)(23C 100C) Take a screenshot of your graph (make sure it has all necessaryelements) and include it in your Lab Report. How much ice will you use? The heat necessary to cause a temperature change, In this article we will go through proper data acquisition and analysis. Calculate the calorimeter constant if 150.0 g of lead at 100.0C were placed in a calorimeter with 50.0 g of water at 22.0C and the resulting temperature of the mixture was 26.2C, you can obtain the specific heat capacities for lead and water from table 5.2.1. To make this possible your TA will be using Raspberry Pi and Vernier temperature probe.
