Physical Science 20 - April 21

Today we learned how to calculate the heat involved in changing phases of different substances.  Much like yesterday's lesson, this is dependent on the mass of the substance involved and the type of the substance.  It is not dependent on a temperature change however as phase changes do not involve a temperature change.  Students copied down notes today on slides 12-19 and worked on Assignment H2 for the remainder of the class. I will check this tomorrow and then we will start combine these 2 types of problems.
