Gold 🔒

This 12-question quiz digs into gold, its physical properties, and how its purity is measured.

You will answer fill-in-the-blank and true or false items, with prompts such as How many carats are there in pure gold? and What metal dissolves gold?

A striking fact is that gold is the most malleable metal there is, soft enough to be hammered into sheets so thin that they are known as gold leaf.

You will also learn about the acid test used to tell real gold apart from other metals, and what white gold actually is.

Recommended level: intermediate.
