what is the definition of physical property in chemistry?
235982
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties.

The same element has different physical properties in different phases or in different compounds. Chemical properties describe a substance's ability to react and form new substances. They can only be tested by reacting the material with other things to see how it changes.

['Physical Properties:', 'Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.', 'Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.']

Determination of chemical properties results in the change of the identity of the substance. Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of substance being examined. These properties are known as intensive properties and are used to identify a substance.

All properties of matter are either extensive or intensive and either physical or chemical. ... For example, the freezing point of a substance is a physical property: when water freezes, it's still water (H2O)—it's just in a different physical state.
1311173
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.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. ... To identify a chemical property, we look for a chemical change.
932705
Physical properties are those in which the chemical formula does not change. ... Physical properties include magnetism, density, molecular mass, viscosity. Chemical properties include combustion, dimerization, polymerization, and reaction with HCl.

What is the difference between physical and chemical properties? A physical property is an aspect that can be observed or measured without being changed. A chemical property may only be observed by changing the chemical identity or substance.
64427
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
445691
Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. ... Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
