what is the difference between physical and chemical properties of a substance?
38730
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. A chemical property describes the ability of a substance to undergo a specific chemical change.

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.

Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity. Chemical properties can be measured only by changing a substance's chemical identity.

One way of classifying a substance (that is, matter) is by its physical properties. ... Examples of physical properties could include size, shape, color, mass, volume, density, texture, phase, melting point, boiling point, hardness, conductivity, or viscosity.

Summary. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.

A chemical property is any of a material's properties that becomes evident during a chemical reaction. A physical property is any measurable property whose value describes a state of a physical system . Color is rather a physical property than a chemical property.

Chemical properties are properties that can be observed or measured when a substances undergoes a chemical change. Physical properties are properties that can be observed without bringing a chemical change.

In a physical change, one or more a of substance's physical properties – its size, shape, color, or state (phase) of matter – is altered. ... A chemical change results in the formation of one or more new substances. The new substances differ in chemical properties and composition from the original substance.

A physical property is a characteristic of matter that can be observed and measured without changing the chemical identity of the sample. The measurement of a physical property can change the arrangement of matter in a sample but not the structure of its molecules.

Mass, color, shape, volume, and density are some physical properties. ... Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies. Chemical properties- These are properties that can only be observed by changing the identity of the substance.

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.

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 a chemical and physical change? Chemical changes involves the production of an entirely new substance through breaking and rearranging atoms. Physical changes are usually reversible and do not involve the creation of different elements or compounds.
