Cards in this deck (32)
- 1Only iron and steel rust. What happens to other metals?Only iron and steel rust. Other metals corrode.
- 2What two things can accelerate rusting?Acid rain and salt water accelerate rusting.
- 3What is rusting?Rusting is an oxidation reaction.
- 4Why is rusting this?Rusting is an oxidation reaction because iron reacts with oxygen forming an oxide.
- 5What is the word equation for rusting?iron + oxygen + water → hydrated iron(III) oxide
- 6Why does aluminium not corrode in moist air?Aluminium does not corrode is moist air because it has a protective layer of aluminium oxide which, unlike rust, does not flake of the surface.
- 7Fill the gaps: Different metals ....... at ......... rates.Different metals corrode at different rates.
- 8Different materials are used in cars because they have different properties. What is aluminium used for?Aluminium is used in car bodies and wheel hubs.
- 9Why is aluminium used?Aluminium is used in car bodies and wheel hubs because it does not corrode, has a low density, is malleable and quite strong.
- 10What is iron or steel used in when making cars?Iron or steel is used in car bodies.
- 11Why is it used for this?Iron or steel is used in car bodies because it is malleable and strong.
- 12What is copper used in when making cars?Copper is used in electrical wires.
- 13Why is it used for this?Copper is used in electrical wires because it is ductile and a good electrical conductor.
- 14What is lead used in when making cars?Lead is used in lead-acid batteries.
- 15Why is it used for this?Lead is used in lead-acid batteries because the chemical reaction with lead oxide produces electricity.
- 16What is plastic used in when making cars?Plastic is used in dashboards, dials and bumpers.
- 17Why is it used in this?Plastic is used in dashboards, dials and bumpers because it is rigid, does not corrode and is cheap.
- 18What is PVC used in when making cars?PVC is used in metal wire coverings.
- 19Why is it used in this way?PVC is used in metal wire coverings because it is flexible, does not react wire water and is an electrical insulator.
- 20What is glass and plastic/glass composite used in when making cars?Glass and plastic/glass composite is used in windscreens.
- 21Why is it used in this way?Glass and plastic/glass composite is used in windscreens because it is transparent and shatterproof (may crack).
- 22What is fibre used in when making cars?Fibre is used in making seats.
- 23Why is it used in this way?Fibre is used in making seats because it can be woven into textiles, can be dyed and is hard-wearing.
- 24What are alloys?Alloys are mixtures of elements containing at least one metal, and often have different and more useful properties than the metals they are made from.
- 25Give an example of an alloy and its more useful properties.Steel
- is harder and stronger than iron
- is less likely to corrode than iron. - 26Car bodies can be built from aluminium or steel and there are advantages and disadvantages with each. Give two advantages of using aluminium for building car bodies.Aluminium is lighter and more resistant to corrosion than steel.
- 27Give two advantages of using steel in building car bodies.Steel costs less than aluminium and is stronger.
- 28Give another advantage of having a lighter aluminium body.A lighter aluminium body means that fuel economy is improved.
- 29If aluminium is used why also will the car body last longer?Because aluminium corrodes slowly, the car body will also last longer.
- 30Give four advantages of recycling the materials from old cars.Advantages of recycling the materials from old cars include:
- less mining saves finite resources needed to make metals
- less crude oil is needed to make new plastics
- less waste means less landfill
- fewer toxic materials, such as lead from batteries, are dumped. - 31Give four disadvantages of recycling the materials from old cars.Disadvantages of recycling the materials from old cars include:
- fewer mines are built and fewer mining jobs created
- difficult to separate the different materials
- some separating techniques produce pollution
- some recycling processes are very expensive. - 32There are laws that specify what to help protect the environment?There are laws which specify that a minimum percentage of all materials used to manufacture cars must be recyclable to help protect the environment.
