Question

Which is not a physical property? hardness boiling point ability to conduct electricity ability to combine with hydrogen

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

A property that does not bring any changes in the chemical composition of a substance is known as a physical property.

For example, hardness, density, boiling point, conductive nature etc are all physical properties.

On the other hand, a property that brings changes in the chemical composition of a substance is known as a chemical property.

For example, reactivity, toxicity etc are all chemical properties.

Thus, we can conclude that ability to combine with hydrogen is not a physical property.

Answer 2

What a substance reacts with is not a physical property, but rather a chemical one. The answer is "ability to combine with hydrogen"
