1. Relate observations of diffusion to particle motion and collision in the gas and liquid phases.
2. Relate observations regarding the addition of energy by warming to increased particle motion.
3. Describe the characteristics of solids, liquids and gases in terms of particles and their arrangement: use particle diagrams to account for motion and density differences; describe the process of how the arrangement of particles changes during phase changes.
4. Relate temperature to the thermal energy (Eth) of particles in motion.
5. Explain, at the particle level, how a thermometer measures the temperature of the system
6. State the basic tenets of the Kinetic Molecular Theory (KMT).
7. The 3 variables P, V and T are interrelated. Any factor that affects the number of collisions has an effect on the pressure. You should be able to:
· Predict the effect of changing P, V or T on any of the other variables.
Explain (in terms of the collisions of particles) why the change has the effect you predicted.
· Explain the basis for the Kelvin scale. Use the absolute temperature scale to solve gas problems.
· Use factors to calculate the new P, V or T. Make a decision as to how the change affects the variable you are looking for.
