P4 syllabus statements

  1. 1. 02/06/14 P4 Simple kinetic molecular model of matter Syllabus statements
  2. 2. 4.1 States of Matter 1. State the distinguishing properties of solids, liquids and gases.
  3. 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. 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. 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. 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. 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.
