Unit 2 - Energy and States of Matter

Objective 2 - Diffusion

Essential Question - How do particles move? Why does this movement cause diffusion to happen?

Learning targets -

1) What is diffusion?

2) How is diffusion related to particle motion and collision in the liquid and gas phases?

Objective 3 - Energy and Particle motion

Essential Question - How does energy affect the motion and arrangement of particles?

Learning targets -

• How does adding energy to particles change the motion of particles?
• Describe the characteristics of solids, liquids, and gases in terms of particles and their arrangements
• Use particle diagrams to account for motion and density differences
• Describe the process of how the arrangement of particles changes during phase changes

Objective 6 Materials

Pressure, Introductory Chemistry, BC Open Textbook Project (reading)

Gas Pressure: The Basics (Tyler DeWitt YouTube video, 12 minutes)

Supplementary - Pressure and the Simple Mercury Barometer (Khan Academy video)

Objective 7 - Kinetic Molecular Theory

Essential Question - What are the basic ideas of kinetic molecular theory?

Objective 7 Materials

The Kinetic Molecular Theory of Matter (reading)

Objective 8 Materials

Objective 9 - Pressure, volume, temperature calculations

Essential Question - How do we use factors to calculate how pressure, volume, and temperature change as functions of each other?

Learning targets -

• Use the absolute temperature scale to solve gas problems
• Use factors to calculate new P, V, or T
• Make a decision as to how the change affects the variable you are looking for.
