Heat capacity of metal lab

Our class did an experiment to find the specific heat of the metals Cu and Pb. To do this we first heated up our metals using a boiling water bath with the metals in them. This rose the heat of the metal to around 100 degrees (we checked for the exact temp) and then we had water at room temperature wich we were going to dump the metal into. This gave us the known variables of M-water, M-metal, Specific heat of water, Temperature of both before and after, leaving the only unknown variable by the end of the lab to be the specific heat of the metal.

energy and phase change

Our new unit is over phase change and the energy involved with that phase change. One of the bic componenets is using the equation Q=MC(delta)T. Another big component to this unit is the Phase change diagrams and how to read them.
