Physical Science 20 - April 27

Today we went over a couple of examples that showed us how to use Hess's Law.  These examples were different than the ones given in class and allowed us to outline the process of Hess's Law.  After those examples, students then worked on Assignment H4 (Period 2 was assignment the even questions, period 4 was assigned the odd questions) for the remainder of the period.  This assignment will be checked tomorrow.  Tomorrow we are going to be doing Lab H1 on specific heats.
