P1.1 - AQA GCSE Physics Unit 1 - Overview
P1.1 |
The transfer of energy by heating processes and the factors that affect the rate at which that energy is transferred
Energy can be transferred from one place to another by work or by heating processes. We need to know how this energy is transferred and which heating processes are most important in a particular situation.
Candidates should use their skills, knowledge and understanding to: |
■ compare ways in which energy is transferred in and out of objects by heat transfer and ways in which the rates of these transfers can be varied |
Examples should include the design of a vacuum flask, how to reduce the energy transfer from a building and how humans and animals cope with low temperatures. |
■ evaluate the design of everyday appliances that transfer energy by heating, including economic considerations |
Examples include radiators and heat sinks. |
■ evaluate the effectiveness of different types of material used for insulation, including U-values and economic considerations |
Examples include loft insulation and cavity wall
insulation. |
■ evaluate different materials according to their specific heat capacities. |
Examples include the use of water, which has a very
high specific heat capacity, oil-filled radiators and
electric storage heaters containing concrete or bricks. |
This section of the first unit is broken into four sections:
P1.1.1 - Infra Red Radiation
P1.1.2 - Kinetic Theory
P1.1.3 - Energy transfer by heating
P1.1.4 - Heating and insulating buildings
There is also a page suggesting practical experiments that should be carried out during the study of this section.
