Heat Capacity of a Metal Lab
Last week we got to find out the specific heat capacity of a metal and we got to test lead's specific heat capacity. First we set up a hot water bath with a beaker on a Bunsen Burner. Then we took a test tube, weighed it, then filled it 1/3 of the way up with lead, and then weighed it again. We then subtracted the weight of the test tube from the weight of the test tube + lead to find the weight of the lead by itself. Then we added the test tube to the hot water bath and let it come to a boil and let it boil for 5 minutes. Then we took the test tube and poured the lead into a Styrofoam cup of room temperature water, while that was happening we measured how hot the water got when the lead was added. Then we used the mcat = mcat formula to determine the specific heat capacity of the metal.
