Surface Area & Temperature
Physics: AQA GCSE Higher, topic 6.6.3
Surface Area & Temperature
The amount of radiation emitted by a body (object) depends on its surface area and surface temperature.
High surface temperature
- Bodies with a higher surface temperature will emit radiation faster.
High surface area
- Bodies with a large surface area will emit radiation faster.
Test yourself on Surface Area & Temperature
Which of the following is true of emitters?
How does surface temperature affect the rate of emission of radiation?
If one thermometer has a black bulb and the other has a shiny foil bulb, which will have the higher temperature if both are heated?
