Sylwester Czado 12-11-07 PHY 185 Lab, Formal Report Lab #10- Calorimetry and Conservation of Energy Purpose: To verify that the equation m water C water ∆T water = m metal C metal ∆T metal is true for Conservation of Energy. │C 1 m 1 (T f -T i ) │ = C 2 m 2 (T f -T i ) Apparatus: Bunsen Burner Triple Beam Balance Thermometer Beaker Metal sample Calorimeter Cup Procedure: 1. First, find the mass of the metal sample and then put it into the boiling water. The metal should not touch the boiling water.

2. Let the metal sample remain in the water for a couple of minutes to make sure that the metal is at the same temperature as the boiling water. 3. Record the temperature. 4. Find the mass of the water in the calorimeter cup and find its temperature. 5. Transfer the metal sample from the boiling water to the calorimeter cup quickly to prevent heat loss. Then dry it carefully. 6. Observe the temperature change of the water. The temperature will increase to its maximum and then decrease to room temperature. 7. The final temperature is the maximum it reaches before beginning to fall. 8. Find the value of each side of m water C water

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
