  1. 2(a)6 marks· CSEC Physics · 1988 · Paper 2State and explain THREE features of the design which could reduce the amount of solar radiation entering the building during the day and hence reduce cooling costs.
  2. 1(a)3 marks· CSEC Physics · 1992 · Paper 2Identify air, mercury, and aluminium as good or poor thermal and electrical conductors by writing 'GOOD' or 'POOR' in the spaces provided.
  3. 1(b)(i)1 mark· CSEC Physics · 1992 · Paper 2Indicate on the diagram by means of an arrow, the direction of heat flow between the mixture and the ice/salt.
  4. 1(b)(ii)2 marks· CSEC Physics · 1992 · Paper 2Explain why the inner container is made of a good thermal conductor while the outer container is made of a poor thermal conductor.
  5. 3(c)3 marks· CSEC Physics · 1995 · Paper 2One of the reasons for having a glass cover over the collector plate of the solar water-heater, shown in Figure 4, is to take advantage of the glass-house (or green-house) effect. Explain the glass-house effect.
