Question

1. What does a physical property describe about a substance?

Answer 1

A physical property describes characteristics of a substance that can be observed or measured without changing the substance's chemical identity. These properties include attributes such as color, odor, melting point, boiling point, density, solubility, hardness, and conductivity. Physical properties can be used to identify substances and can change under different conditions, such as temperature or pressure, but the substance itself remains unchanged in terms of its chemical composition.
