Test on Metals and Non-metals: Properties and Uses

Question 1: Copper and nickel are metals used for creating coins.

A. Ano

B. Ne

Explanation: The study materials explicitly state under 'The Marvelous Uses of Metals' that 'Metals like copper and nickel are used to create coins.'

Question 2: Is it true that all metals rust when exposed to the elements?

A. Ano

B. Ne

Explanation: The study materials explicitly state that 'Only iron rusts,' implying that not all metals are subject to rusting.

Question 3: According to the provided study materials, which of the following statements accurately describes the property of shininess in metals?

A. Shininess is a property that allows metals to be hammered and shaped without breaking.

B. The gleam and sparkle of metals contribute to their visual appeal.

C. Shininess helps to protect metals from corrosion.

D. Shininess is the primary reason metals are known for their hardness and strength.

Explanation: The study materials state that 'One of the standout features of metals is their shininess. When you think of metals, you probably imagine objects that gleam and sparkle, like gold and silver. This quality not only makes them visually appealing but also helps protect them from corrosion.' Therefore, options 1 and 2 are correct. Option 0 describes malleability, not shininess. Option 3 incorrectly links shininess to hardness and strength, which are distinct properties.

Question 4: Which specific property of metals, as described in the study materials, makes them ideal for constructing sturdy structures like buildings and bridges?

A. Their high melting points, suitable for applications involving extreme heat.

B. Their ability to be stretched into thin wires without breaking.

C. Their capacity to withstand heavy loads and resist bending or breaking under pressure.

D. Their shininess, which helps protect them from corrosion.

Explanation: The study materials state that metals are known for their hardness and strength. They can withstand heavy loads and resist bending or breaking under pressure, which makes them ideal for constructing sturdy structures like buildings and bridges.

Question 5: Ceramic and glass, which are non-metals, are utilized in the production of cookware.

A. Ano

B. Ne

Explanation: The study materials explicitly state under 'Unique Uses of Non-Metals' that 'Non-metals like ceramic and glass are used in cookware, ensuring even heating and easy cleaning.'
