Preparation - Chapter 4.1a, Chapter 4.1b

Participation - Assignment P.109 Q9

Presentation - Blackboard, Student's Work

Possession
> Heat conduction is the transfer of heat by molecular collisions (P.107).
> In general, heat conduction in SOLID > LIQUID > GAS
> Water is NOT a good conductor of heat.
> Air is a poor conductor / Air is an insulator of heat.
> Applications of conduction (P.103)

Preparation - Chapter 4.2

Participation - Assignment P.118 Q2, 4, 6, 8 and P.135 Q18, 27, 28

Presentation - Blackboard, Student's Work

Possession
> Draw a labelled setup of demonstration of convection of liquid and air
> Applications of convection 9P.112)
> Transfer of heat by convection in fluid is always stronger than that by conduction.

Preparation - Chapter 4.3a, Chapter 4.3b

Participation - Assignment P.132 Q5, 4, 7, 9 and P.135 Q20, 21, 23-26, 30-33, 35-36, 38, 39

Presentation - Blackboard, Student's Work

Possession
> Rate of heat transfer by radiation depends on temperature difference and colour of hot surface and surface area (how?)
> Applications of heat radiation
> Black surface is a better radiator (for a hot object)
> Black surface is a better absorber (for a cold object)
> Explain Vacuum flask and Green house effect in consideration of heat conduction, convection and convection.
