Thermal Energy conservation lab

I expect, or at least, would like, a brief but formal writeup showing that you know you were trying to demonstrate the conservation of thermal energy. You did this by collecting data and using it in a conservation based equation to determine the specific heat of your sample. If the specific heat came out close to the standard value, it confirms that your equation which was based on conservation of thermal energy was correct.

You should definitely include both the original equation relating loss of energy of the meatl to gain of energy by water/container AND the rearranged equation for cmetal = etc.

Standard values: brass about 390 J/ (K kg); iron 440 J/ (K kg); Aluminum 920 J/ (K kg)
