Question

A. Gold is too soft alone
B. Gold is cheaper than silver
C. Gold has a higher melting point
D. Gold is a better conductor

Answer

Gold is too soft alone

Explanation

Gold alloys are used in jewelry because pure gold is too soft for everyday wear, and alloying it with other metals increases its strength.

Common mistake

Misunderstanding Alloy Uses

Students often confuse the uses of different alloys, such as thinking that bronze is used for plumbing instead of brass.

To fix this, students should create a chart listing each alloy along with its specific uses, such as bronze for sculptures, brass for plumbing, and stainless steel for cutlery.
