Radiation P1

What are the three methods of heat transfer? • Conduction • Convection • Radiation
What are the main transfer methods through: a) Solids b) Liquids and gases? a) Conduction b) Convection
What is the link between temperature difference and rate of energy transfer? The bigger the temperature difference between and object and its surroundings the faster the rate of transfer of heat energy
What happens to the rate of transfer if an object is: a) Hotter than its surroundings b) Cooler than its surroundings? a) The faster the rate of transfer of heat energy b) The slower the rate of transfer of heat energy
Why? Because if an object is hotter, it radiates more radiation than if its cooler.
Why is matt black a good colour to use for some appliances? Because it absorbs and emits radiation better than shiny surfaces
What is a use of matt black surfaces? Explain why. Solar hot water panels with water pipes on a black surface absorb radiation to heat water in pipes, then pumped around the radiators etc.
Why are silver, shiny surfaces useful in some appliances? Because they reflect the radiation falling on them
Give a use of shiny surfaces and explain why its useful. Vacuum flasks have silver shiny surfaces on the inside of them to keep heat in or out depending whether they are holding hot or cold water
