2 . Which statement is not correct? luminium is used in food containers because of its resistance to corrosion. luminium is used in the manufacture of aircraft because of its strength and low density. Mild steel is used in car bodies because of its strength and low density. Stainless steel is used in chemical plant because of its strength and resistance to corrosion. The diagrams show what happens when three different metals are added to water. bubbles of gas flame X Y Z What are X, Y and Z?

3 . Some properties of aluminium are listed. 4 It has mechanical strength. It is resistant to corrosion. It has a low density. It conducts heat. Which three properties make aluminium useful for making the bodies of aircraft?, and, and 4, and 4 4. Which statement about the uses of metals is correct? luminium is used in the manufacture of aircraft because of its strength and high density. opper is used in electrical wiring because of its strength and high density. Mild steel is used in the manufacture of car bodies because of its strength and resistance to corrosion. Stainless steel is used in the construction of chemical plant because of its strength and resistance to corrosion. 5. opper is sometimes used to make cooking utensils. saucepan gas ring Three properties of copper are given. corrosion resistant good conductor of electricity good conductor of heat Which properties make copper a suitable metal for making cooking utensils? and only and only

4 6. opper is a transition element used to make saucepans. Which property is not correct for copper? good conductor of heat insoluble in water low melting point malleable (can be hammered into shape) 7. The bodies of aircraft are often made using aluminium. Which two properties of aluminium make it suitable for this use? property property good conductor of electricity good conductor of electricity good conductor of heat strong good conductor of heat strong low density low density 8 luminium is an important metal with many uses. Some of its properties are listed. It is a good conductor of heat. It has a low density. It has an oxide layer that prevents corrosion. Which set of properties help to explain the use of aluminium for cooking and storing food? only and only and only, and 4

5 9 Which uses of the metals shown are both correct? aluminium aircraft bodies car bodies chemical plant food containers stainless steel cutlery aircraft bodies food containers car bodies 0 Iron is a metal that rusts in the presence of oxygen and water. Mild steel is used for... and is prevented from rusting by.... Stainless steel does not rust. It is produced by... iron with another metal. Which words complete gaps, and? Which row describes how the metals are used? 5

6 Metal M is mixed with copper to produce brass. What is M? chromium nickel vanadium zinc. Two experiments are carried out. In experiment, copper is heated with steam. In experiment, copper(ii) oxide is heated with carbon. steam copper(ii) oxide and carbon copper experiment heat experiment Which row describes what happens in experiments and? 6

7 4 Steel is made by adding to molten iron to remove from the iron. Stainless steel is resistant to corrosion than mild steel. Which words complete the gaps, and? 5 The diagram shows a section of an overhead power cable. steel ceramic aluminium Which statement explains why a particular substance is used? luminium has a low density and is a good conductor of electricity. eramic is a good conductor of electricity. Steel can rust in damp air. Steel is more dense than aluminium. 7

8 6 rass is an alloy of two metals. Which row gives a correct use for the two metals from which brass is made? metal metal used for electrical wiring used for galvanising steel used for making aircraft used for making cooking pans used for galvanising steel used for making aircraft used for making cutlery used for electrical wiring 8
