.07 CALORIMETRY VIRTUAL LAB /100 points Purpose [Place your name here] To examine the concept of heat and to calculate the amount of heat that transfers between two objects. Heat is defined as the energy transfer between an object that is warm and an object that is cooler. Check out The Physics Classroom for some background information. In this lab, you will perform calculations with specific heat capacity using a(n) simulation/applet of the calorimeter. Equation background Q = mcAT The heat (Q) can be found by multiplying the mass of the substance (m) times the specific heat (heat capacity) of the substance (c) times the change in temperature that the substance undergoes (AT). Units may vary, but it may be easiest in this activity to use calories for the units of heat. A calorie is defined as the amount of heat required to raise the temperature of one gram of water one degree Celsius. (1 calorie = 4.19 J) The specific heat of water is 1 cal/gC. The temperature change would be in C. Materials: Link for Lab Calorimetry Procedures: 1. To become familiar with the applet start by selecting \"silver\" from the list of metals in the solids tab. All metals should have a mass of 50 g. . In the metals box, move the mass slider to the right until it reads \"50.0 g."\" All metals should be at an initial temperature of 100 C. . In the metals box, move the temperature slider to the right until it reads *100 C." Click 'Show specific heat' Click \"Next', and then select water from the list of liquids. Choose the mass and temperature of the water as \"50.0 g\" and \"20.0 C." You will also want to click \"Show specific heat'. Click "Next' and then check 'Show graph view'. Then click \"start and record the final temperature in a data table 10. Click \"reset\" and repeat the process for Unknown metals | and Unknown metal Il. . N oA WN Data: 1. Create an appropriate data table for all three metals - including the data for the water in each trial. Your table should organize all your data (the name, mass, specific heat, measured temperatures, etc.) (40 points) Calculations: 1. Calculate the heat (Q) gained by the water. Use this value as the heat (Q) lost by the metal and from that calculate the theoretical value of the final temperature of the silver. Show your work, (20 points) This video may be helpful. hitps://www. youtube com/watch?v=|IsBOI7BORI 2. Calculate the percent error for the final temperature you calculated and the one you got from the lab results. Show your work, (10 points) 3. Calculate the specific heat capacity for each of the unknown metals. Even though you would be able to see this from the demonstration, show how you would use calculations to find it. Show your work. (15 points) Conclusion: Write an appropriate conclusion for this lab.In your conclusion discuss what you learned from this lab (+4), what specific heat is (+3), and research how it is used. (+3) Read this article. What does it say about the specific heat of metal versus glass baking dishes? (+3)
