ALUMINUM METAL
Pre-weighed Aluminum metal -100 grams sample mass (mmetal)
Temperature of boiling water and metal sample in the pot (Ti(metal)) 365k and 345k
Temperature of cool water in the calorimeter prior to adding hot metal sample (Ti(water)) 364k
Maximum Temperature of water/metal in calorimeter after mixing (Tf) 365k LEAD METAL
Pre-weighed Lead metal sample mass (mmetal) 50g
Temperature of boiling water and metal sample in the pot (Ti(metal)) 365k & 340k
Temperature of cool water in the calorimeter prior to adding hot metal sample (Ti(water)) 364.8k
Maximum Temperature of water/metal in calorimeter after mixing (Tf) 365k IRON METAL
Pre-weighed Iron metal sample mass (mmetal) 60g
Temperature of boiling water and metal sample in the pot-365K & 330k
(Ti(metal))
Temperature of cool water in the calorimeter prior to adding hot metal sample (Ti(water)) 364.3k
Maximum Temperature of water/metal in calorimeter after mixing (Tf) 365k
Calculations (show work for all calculations)
Aluminum Sample:
Calculate the change in temperature for the water caused by the addition of the aluminum by subtracting the initial temperature of the water from the final temperature of the water. ΔT = Tf - Ti (5 points)
ΔT = Tf - Ti =1.29 degrees celcius
Calculate the change in the metal’s temperature by subtracting the initial temperature of the aluminum from the final temperature of the aluminum. ΔT = Tf - Ti (5 points)
Determine the mass of the water by using the water’s density (specific to the initial temperature) and the volume of the water. Remember, density = mass/volume. You can look up the density of the water at your specific temperature. (5 points)
Use the equation: q = m(SH)ΔT to solve for the amount of heat gained by the water from metal. You have the mass of water from
