Results/Calculations: Part 2 - Determine Calorimeter Constant, B, using equation 6: BATew+MewCinoATew+MCHOAT=0 a. Rearrange Equation 6 to solve for the calorimeter constant, B b. Using your data, find the mass of the cold water, M. for each trial. c. Using your data, find change in temperature of the cold water (ATew=Tfinal mix-Tool) for each trial d. Using your data, find the mass of the hot water, Ms for each trial e. Using your data, find change in temperature of the hot water (AT=Tfinal mix-Tboiling water) for each trial f. Now that you have all the variables, use your equation from part a to solve for the calorimeter constant, B for each trial (You can find the specific heat capacity of water in the prelab) g. Find the average calorimeter constant average B 121
Part 3- Determine specific heat of metal, Cm, using equation 5 BATew MewCH20ATew+MmCmATm=0 a. Rearrange Equation 5 to solve for the specific heat of the metal, Cm b. Using your data from Part 3, find the mass of the cold water, Mew for each trial. c. Using your data from Part 3, find change in temperature of the cold water (ATew= Tfinal mix-Tcool) for each trial d. Using your data from Part 1, find the mass of the metal, Mm for each trial e. Using your data from Part 3, find change in temperature of the metal (ATm = Tfinal mix- Tboiling water) for each trial
f. Now that you have all the variables (B is the average calorimeter constant you found in Part 2 and you can find the specific heat capacity of water in the prelab), use your equation from part a to solve for the specific heat of the metal, Cm for each trial g. Calculate the Average Value for Cm (with units) Average Cm: Using Provided List of Metals and their specific heats determine the identity of your unknown metal Unknown Metal Identity:
