The metals that we had to choose from were, Stainless steel, Lead(Pb), Aluminum (Al), Brass, Copper (Cu), Zinc (Zn) and Water. The substance that we got was lead, the reason why is that lead is one of the only metals that is made into fishing weights. And it is pretty flexible as well. What we had to learn or know to do this lab is the Variables and the equations for this lab. We had to find out what the temperature was and how to find the temperature with a scientific thermometer. And how to record the mass and to get the metal to heat up to give a temperature before being heated and after being heated.

Good description, JOhn. Do you have any masses, temperatures? You need to calculate the specific heat of the metal, then compare to the list of known metals you were given.
ReplyDeleteMrs. Lee I have done everything in the post except that on my lab book, I do not have the measurements and or the calculations from my lab because the lab book is with you. I do believe my measurements are in my lab book. But I have done everything else.
