Question 5

Define sonorous:

Answer 5

A word to describe a metallic substance that rings like a bell when hit with a hammer

Question 6

Define alloys:

Answer 6

Mixtures of elements (usually metals) designed to have the properties useful for particular purpose
Ex. solder (an alloy of tin and lead) has a low melting point

Question 7

Define brass:

Answer 7

An alloy of copper and zinc, this alloy is hard

Question 8

Define stainless steel:

Answer 8

An alloy of iron that resists corrosion
The steel contains a significant proportion of chromium which results in the alloy being resistant to rusting
