 * Chapter T1: Simple Kinetic Molecular of matter **

(a) Compare the properties of solids, liquids and gases. (b) Infer from Brownian motion experiment the evidence for the movement of molecules. (c) Describe qualitatively the molecular structure of solids, liquids and gases, relating their properties to the forces and distances between molecules and to the motion of the molecules. (d) Describe the relationship between the motion of molecules and temperature. (e) Explain the pressure of a gas in terms of the motion of the molecules. (f) Recall and explain the following relationships using the kinetic model (stating of the corresponding gas laws is not required) · a change in pressure of a fixed mass of gas at constant volume is caused by a change in temperature of the gas · a change in volume of a fixed mass of gas at constant pressure is caused by a change in temperature of the gas · a change in pressure of a fixed mass of gas at constant temperature is caused by a change in volume of the gas Use the relationships stated above to solve problems (qualitative treatment would suffice) (g) Show understanding that at absolute zero, particles have minimum energy and that the system neither emits nor absorbs energy.

(a) Show understanding that thermal energy is transferred from a region of higher temperature to a region of lower temperature until thermal equilibrium is achieved. (b) Describe, in molecular terms, how energy transfer occurs in solids. (c) Describe, in terms of density change, convection in fluids. (d) Explain that energy transfer of a body by radiation does not require a material medium and the rate of energy transfer is affected by (e) Apply the concept of thermal energy transfer to everyday applications.

(a) Explain how a physical property which varies with temperature may be used to define temperature scale and state examples of such properties. (b) Explain the need for fixed points and state what is meant by ice point and steam point. (c) Explain how a temperature scale is constructed. (d) Discuss the structure, sensitivity, range, linearity and responsiveness of liquid-in-glass thermometers. (e) Discuss the action of a thermocouple thermometer, showing an understanding of its use for measuring high temperatures and temperatures which varies very rapidly.

 * 6 || **Chapter T5: Thermal Properties**

(a) State that internal energy is the total potential and kinetic energy of molecules in a substance. Students should know that the kinetic energy of the molecules arises from their translational/rotational motion and that the potential energy of the molecules arises from the forces between the molecules. (b) Describe a rise in temperature of a body to an increase in internal energy (random thermal energy). (c) Define the terms heat capacity and specific heat capacity (d) Recall and apply the relationship thermal energy = mass x specific heat capacity x change in temperature to new situations or to solve related problems Lab Practical T5: SHC of a brass [|Practical T5_shc of metal.doc]

The presentation in week 9 must include a short video demonstration of their appliance working. || (continued) (a) Define the terms latent heat and specific latent heat. (b) Explain latent heat in terms of molecular behaviour. (c) Recall and apply the relationship thermal energy = mass x specific latent heat to new situations or to solve related problems.

 * 9 || **__Presentation Week!__**

A 9 minute presentation of each team must include:

 * Design of appliance
 * Physics in the design
 * Video demonstration of the appliance working

After the presentation, each team must submit a web report of their PBL in their group portfolio in wikispace. The web report should include the details of their presentation.

Each member of the team must submit a individual reflection sheet containing the following information:
 * What have I learn from Solar Energy PBL?
 * Did my team work well together? Explain.
 * Which aspect could my team have done better?
 * Rate your team mates' contributions (1 being lowest, 5 being the most)
 * Rate your own contributions (1 being the lowest, 5 being the most) ||
