Virtual Specific Heat Lab PURPOSE: Calculate the specific heat of an unknown metal and use this number to correctly identify the metal. Use the simulation provided here PROCEDURE: Follow directions and show work for all calculations. A. Select Iron as the first metal to be tested. B. Select 50.00g of iron heated to 100 C. C. Select 100.00g of water at a temperature of 20 C. D. Click start to begin the experiment. Wait until the temperature stops rising, then record the final temperature below: T final 1. Determine the change in temperature for the water and the iron. Use the same final temperature for both the iron and the water. AT (water) AT (iron)= 2. Calculate the heat gained by the water. Use Q=mCAT, solving for Q (heat) and inserting m (mass of water), C (specific heat of water = 4.184 J/g .C), and AT (change in temperature for water). E. Now select unknown metal X( X= I or II) as the metal to be tested. F. Select 50.00g of metal X heated to 100 C. G. Select 100.00g of water at a temperature of 20 C. H. Click start to begin the experiment. T final NB repeat the experiment for the same metal with 3 different masses. For each: 3. Determine the change in temperature for the water and the metal. Use the same final temperature for both the metal and the water. AT (water)= AT (metal X)= 4. Calculate the heat gained by the water. Use Q=mCAT, solving for Q (heat) and inserting m (mass of water), C (specific heat of water = 4.184 J/g .C), and AT (change in temperature for water). 5. Since the heat gained by the water is equal to the heat lost by the metal, we can use this value to determine the specific heat of the unknown metal. (Determine the specific heat and the error associated, whether there is any, between the three experiments) (m metal Cmetal AT metal = m water C water AT water )6. Use the table of specic heats to determine the identity of your unknown metal. Metal X is manl-n Em_ _ Practice Problems: 1. A sample of water changes temperature from 80.0 C to 20.0 C. Calculate AT. 2. How much energy is required to raise 57.1 grams of water from a temperature of 36.5 C to 66.9 C? 2. What mass of magnesium is present if 250 J raises the temperature from 25 C to 27 C? (Use the chart). 3. What is the heat capacity of an unknown metal if 65.5 grams absorbs l550 J and undergoes a temperature change of 62.0 C? 4. A beaker contains 125.0 grams of water at 22.0 C. A small piece of metal with a mass of 38.2 grams is in another beaker of boiling water, measured at 102 C. When the metal is removed and added to the cooler water, the nal temperature is 23.3 C. What is the specic heat of the metal? What is the metal
