Heat Capacity of Brass and Aluminum Introduction: In our lab, we heated up two different masses of both brass and aluminum in an attempt to find the C of the metal. In order to see if different masses of the same metal have the same Heat capacity, we re-arranged the equation to solve C of the Metal, Cmetal = Qrxn / (mass)( t). Procedure: We got to pieces of the same metal that had different masses. We had a beaker of water at room temperature sitting and waiting. We then heated the metal in a beaker of water until the water reached its boiling point. Also in the water was a set of tongs heating, we used the tongs and moved the piece of metal quickly into a the room temperature water, and recorded the temperature in 30 second intervals. We did this twice for each different metal sample. The metal was added at the 3 minute mark each time.

### What students are saying

• 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.
