Sample questions

1. What is the property of materials that allows them to be drawn into wires?

   1. Brittleness
   2. Ductility
   3. Malleability
   4. Hardness
   Show answer

   Answer: B. Ductility

   Ductility is the property of materials that allows them to be stretched into wires without breaking.

2. What do we call the ability of a material to resist scratching?

   1. Toughness
   2. Hardness
   3. Brittleness
   4. Malleability
   Show answer

   Answer: B. Hardness

   Hardness refers to a material's resistance to being scratched, with harder materials being able to scratch softer materials.

3. Which of these materials would be suitable for making a strong bridge?

   1. Plastic
   2. Cardboard
   3. Steel
   4. Wood
   Show answer

   Answer: C. Steel

   Steel is a strong material that can support heavy loads, making it ideal for constructing a bridge.

4. What happens to a metal rod when heated?

   1. It contracts
   2. It expands
   3. It becomes electric
   4. It breaks down
   Show answer

   Answer: B. It expands

   When a metal rod is heated, the particles vibrate more and take up more space, causing the rod to expand.

5. In terms of intermolecular forces, which of the following substances is likely to have a low boiling point?

   1. Water
   2. Sand
   3. Oxygen
   4. Iron
   Show answer

   Answer: C. Oxygen

   Oxygen has weak intermolecular forces compared to substances like water and iron, which is why it has a low boiling point.
