Detailed explanation-1: -Physical properties are those which can be observed or measured without changing the composition of matter. They are used to observe and describe matter. Texture, colour, odour.
Detailed explanation-2: -Physical properties refer to properties that can be observed or measured without changing the composition of the material. Examples include colour, hardness and smell and freezing, melting and boiling points.
Detailed explanation-3: -Physical properties are those which can be measured without changing the identity of a substance. Color, hardness, volume, density, malleability, solubility, boiling, and melting points are some of the physical properties.
Detailed explanation-4: -All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample).
Detailed explanation-5: -Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
