Unit Seven:  Gas Laws 

• Knows the structure and the properties of matter

•      Knows that the physical properties of a compound are determined by its molecular structure and the interactions among these molecules (SC.5.9-12.5)

• Knows how the Kinetic Molecular Theory is used to describe gas properties.
• Is able to relate how gas pressure and temperature is able to relate movement of the gas particles

Unit Eight:  Phase Changes…. Bonds and Energy

• Knows the structure and the properties of matter
• Knows that the physical properties of a compound are determined by its molecular structure and the interactions among these molecules (SC.5.9-12.5)
• Phase changes
• Relate viscosity, cohesion, adhesion, surface tension, capillary action, boiling points to intermolecular bonds
