This section covers the following syllabus (Physics 5059) requirements.
show understanding that thermal energy is transferred from a region of higher temperature to a region of lower temperature
describe, in molecular terms, how energy transfer occurs in solids
apply the concept of thermal energy transfer (conduction) to everyday applications
This section covers the following syllabus (Physics 5059) requirements.
describe, in terms of density changes, convection in fluids
apply the concept of thermal energy transfer (convection) to everyday applications
This section covers the following syllabus (Physics 5059) requirements.
explain that energy transfer of a body by radiation does not require a material medium and the rate of energy transfer is affected by:
(i) colour and texture of the surface
(ii) surface temperature
(iii) surface area
apply the concept of thermal energy transfer (radiation) to everyday applications
