Physical Science 20 - April 14

Today in class we learned how to calculate the heat involved in not only going through phase changes but also temperature changes as well.  This involved using multiple equations to calculate the change in heat at different temperature points.  You just have to understand what those temperature points are.  That being said, we will just be using water for this since we know the melting/freezing and boiling/condensing points well.  We went through a couple of examples and then spent the rest of class working on Assignment HT3.  We will go over this tomorrow and then move on to enthalpy.  The notes covered today were on slides 19-26 of the measuring heat powerpoint.
