10/14 Chemistry update and homework due 10/21

Hi folks,

Today we did a very complicated and detailed lab where we tried to determine the specific heat of lead. Next week we will talk about this a bit more and go over some of these heat problems. We will also add a couple of more things to this heat/temperature concept.

Homework for this week is to finish the lab that you started in class (the specific heat of lead is included in the .pdf). Also, figure out your percentage error. The formula for that is: (your result - correct number)/ actual result. The closer you are to 0% the better. Don't worry if it's a negative number, take the absolute value (in other words, just make it positive).

AND complete the enclosed .pdf. I included the answers at the bottom so that you can test to see if you really understand the problems. These problems will be on an upcoming quiz so be sure to understand them as best as you can. Feel free to email me if you get stuck.
