2. 4.1 States of Matter
1. State the distinguishing properties of solids,
liquids and gases.
3. 4.2 Molecular Model
1. Describe qualitatively the molecular structure
of solids, liquids and gases.
2. Relate the properties of solids, liquids and
gases to the forces and distances between
molecules and to the motion of the molecules.
3. Interpret the temperature of a gas in terms of
the motion of its molecules.
4. 4.2 Molecular Model
4. Describe qualitatively the pressure of a gas in
terms of the motion of its molecules.
5. Describe qualitatively the effect of a change of
temperature on the pressure of a gas at constant
volume.
5. 4.3 Evaporation
1. Describe evaporation in terms of the escape of
more energetic molecules from the surface of a
liquid.
2. Demonstrate understanding of how
temperature, surface area and air flow over a
surface influence evaporation.
3. Relate evaporation to the consequent cooling.
6. 4.4 Pressure Changes
1. Relate the change in volume of a gas to change in
pressure applied to the gas at constant
temperature and use the equation
p V = constant at constant temperature.
7. 4.4 Pressure Changes
1. Relate the change in volume of a gas to change in
pressure applied to the gas at constant
temperature and use the equation
p V = constant at constant temperature.
