In this lesson, we will learn how to identify the uses of metals such as copper, aluminum, and steel based on their physical and chemical properties.
Q1:
Which of the following is not a potential advantage of steel over aluminum?
Q2:
Which one of these elements would you not find in a mobile phone?
Q3:
Metals may be used to transfer thermal energy in heating systems.
Which physical property is most important in the selection of a metal for heating applications?
What metal is most suitable for use in small-scale heating applications?
Q4:
Although steel is sometimes used in place of aluminum in automobiles, aluminum is strongly preferred in aircraft. Which property is most responsible for the difference in the use of metals in these applications?
Q5:
The uses of tin, iron, aluminum, and copper partly depend on their reactivities. Using the elemental symbols, arrange these metals in order of increasing reactivity.
Q6:
Which of the following is not a potential disadvantage of lead relative to tin?
Q7:
Which of the following is a major advantage of copper over steel when used as a roofing material?
Q8:
Which of the following values is generally higher for aluminum alloys than for copper?
Q9:
For the storage of liquids, cans made from tin are often preferred over those made from steel. What is the main advantage of tin over steel in this application?
Q10:
Aluminum and iron have a range of physical and chemical properties. Based on how the two metals differ, which property can be most easily exploited to separate the two metals when they are being recycled?
Q11:
In ancient Rome, water was frequently transported through pipes made from lead.
Which of the following is not a property of lead that makes it more suitable than other structural metals for this application?
The use of water pipes made from lead is now usually avoided. Which potential hazard is mostly responsible for this change?
