P5 syllabus statements P5 syllabus statements Presentation Transcript

  • P5 Matter & Thermal Properties Syllabus statements 02/06/14
  • 5.1 Thermal expansion of solids, liquids and gases 1. Describe qualitatively the thermal expansion of solids, liquids and gases. 2. Explain in terms of motion and arrangement of molecules the relative order of magnitude of the expansion
  • 5.1 Thermal expansion of solids, liquids and gases 3. Identify and explain some of the everyday applications & consequences of thermal expansion. 4. Describe qualitatively the effect of a change of temperature on the volume of a gas at constant pressure.
  • 5.2 Thermal capacity 1. Demonstrate understanding of the term thermal capacity. 2. Describe an experiment to measure the specific heat capacity of a substance. 3. Recall and use the equation: energy = mass × specific heat capacity × change in temperature
  • 5.3 Melting and boiling 1. Describe melting and boiling in terms of energy input without a change in temperature. 2. Distinguish between boiling and evaporation. 3. Describe condensation and solidification.
  • 5.3 Melting and boiling 4. Use the terms latent heat of vaporisation and latent heat of fusion and give a molecular interpretation of latent heat. 5. State the meaning of melting point and boiling point.
