|---|---|---|---|---|---|---|---|---|
| What is a fuel ? | show | e.g. coal, wood, petrol
🗑
|
||||||
| Where does the energy stored in fuels come from ? | show | All living things derive their energy from sunlight.
🗑
|
||||||
| What are fossil fuels ? | show | These took millions of years to form underground.
🗑
|
||||||
| Why are fossil fuels non-renewable ? | They cannot be replaced in our lifetime. | show 🗑
|
||||||
| What are renewable resources? | Wind, wave, tidal, solar, geothermal,hydroelectric. | show 🗑
|
||||||
| What problems are associated with burning fossil fuels ? | show | They will run out someday and they also cause global warming.
🗑
|
||||||
| show | Sokids, liquids and gases. | Although most liquids are poor conductors and so are gases.
🗑
|
||||||
| Metals are good conductors of heat and electricity because . . . | They contain de-localised electrons. | show 🗑
|
||||||
| show | Poor conductors of heat (and electricity) | because they have no 'free' electrons.
🗑
|
||||||
| Poor conductors such as glass and plastic are called . . . | show | They are chosen because they do not conduct well.
🗑
|
||||||
| Convection usually happens in . . . | liquids and gases | show 🗑
|
||||||
| The flow of a fluid (liquid or gas) due to convection is called a . . . | show | Hot fluid is less dense so rises, transporting thermal energy.
🗑
|
||||||
| show | electromagnetic waves, such as light, infra red, radio, etc. | There is no such thing as 'heat waves' in Physics.
🗑
|
||||||
| show | electromagnetic radiation, mainly visible light. | The Sun also radiates UV, IR, radio and X-rays.
🗑
|
||||||
| The Earth absorbs radiation from the Sun. This causes . . . | show | The temperature falls at night when energy is radiated back into space.
🗑
|
||||||
| Every object emits . . . | thermal radiation. | show 🗑
|
||||||
| Infra red radiation can be used in . . . | show | IR is invisible to our eyes, but a digital camera can see it; shine a TV remote at it.
🗑
|
||||||
| Infra red radiation can be detected with a . . . | thermometer with a blackened bulb to absorb the energy. | show 🗑
|
||||||
| show | Radio, microwaves, infra-red, visible, ultra-violet, X-rays and gamma rays. | Visible light is just a very small part of it.
🗑
|
||||||
| The Earth's atmosphere blocks which types of solar radiation? | show | It allows light and some infra red to reach the surface.
🗑
|
||||||
| What is the 'Greenhouse Effect'? | Long wavelength radiation is absorbed and cannot escape. | show 🗑
|
||||||
| show | Water vapour, carbon dioxide and methane. | They strongly absorb infra-red radiation from the Earth's surface.
🗑
|
||||||
| Why is 'Global Warming' such a bad thing ? | show | Low lying areas will be flooded.
🗑
