A student described two properties of a substance as shown.

| Property | Description |
|----------|-------------------------------------------------------|
| A | The substance can be hammered into a flat sheet. |
| B | The density of the substance is one-third of the density of iron. |

Which of the following statements is true about the two properties described in the table?

A. Both are physical properties.
B. Both are chemical properties.
C. A is a chemical property and B is a physical property.
D. A is a physical property and B is a chemical property.



Answer :

To determine the correct statement about the properties described for the substance, we need to understand the nature of each property.

Property A: The ability to be hammered into a flat sheet. This property is known as malleability. Malleability is a physical property because it describes how the substance behaves when a force is applied, without altering its chemical structure.

Property B: The density of the substance is one-third of the density of iron. Density is a measure of mass per unit volume. It is also a physical property because it describes an inherent characteristic of the substance that does not involve a chemical change.

Thus, both properties A and B are physical properties.

Therefore, the true statement about the two properties described in the table is:
Both are physical properties.
