Question

A student described two properties of a substance as shown:

Properties of Substance
Property C: The substance has a density greater than water.
Property D: A substance can be stretched out to become a long wire.
Which of the following is true about the two properties described in the table?
A) Both are physical properties.
B) Both are chemical properties.
C) Property C is a chemical property, and Property D is a physical property.
D) Property C is a physical property, and Property D is a chemical property.

Answer 1

Both described properties, having a greater density than water (Property C) and the ability to be drawn into a wire (Property D), are physical properties because they can be measured or observed without changing the substance's chemical identity.

Step-by-step explanation:

The question refers to two distinct properties of a substance: Property C indicates that the substance has a density greater than water, and Property D that the substance can be stretched out to become a long wire. The correct response is A) Both are physical properties.

Property C, having a density greater than water, is a physical property as it can be measured without altering the substance's chemical identity. Density is an intensive property that reflects the mass-to-volume ratio of a substance.

Property D, the ability of a substance to be stretched into a wire, is related to the physical property of malleability. Malleability is another characteristic that can be observed without changing the substance's chemical structure. Therefore, neither of these properties indicate a chemical change or a chemical property, as they do not involve creating a new substance.
