Combined Gas Law

Having thoroughly explored gas laws involving two variables (Pressure & Volume, Pressure & Temperature, and Temperature and Volume), students were introduced to the Combined Gas Law, k=PV/T, at the end of class yesterday.  We began class with the video below:

Next, students received a copy of a handout designed to accompany the Deriving the Gas Laws activity packet from yesterday.  Students worked with their table partners to review, model, and explain the lab data.  The handout, due at the end of class, included a combined gas law practice problem.  Students had the remainder of the class period to:

  • Read Lesson 61 in the textbook and work through the practice exercises (assigned yesterday)
  • Complete the Lesson 61 worksheet handed out yesterday (due tomorrow, February 21)
  • Read Lesson 64 in the textbook and worth through the practice exercises.

We spent an extra day working through Combined Gas Law problems (class periods were short as a result of the Curriculum Fair).  We reviewed a few problems from the table on th efront of the Lesson 61 Worksheet, and we also worked through question 7 from a handout of additional Gas Law practice problems.  Class notes are shown below:
