chemical properties are characteristics that describe a substance's ability to change into different substances, and physical properties are characteristics that can be observed without changing it into another substance.

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.

Physical properties include odor,taste,appearance,melting point,boiling point etc.. where as chemical properties include the chemical reaction,changes at molecular level.

What is a chemical property? A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

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.

1.3: Properties of Matter. 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).
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.

Physical properties of matter are properties that can be measured or observed without matter changing to an entirely different substance. ... Examples of physical properties of matter include melting point, color, hardness, state of matter, odor, and boiling point.

Characteristics such as mass, volume, color and temperatures are physical properties. Chemical Properties of matter are the ability of substances to react with or change into other types of matter. ... Some characteristics can describe a substance but do not, by themselves, identify the substance.

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.

In this lesson, we looked at some of the more common physical properties of compounds, including color, odor, melting point and boiling point. A chemical property is a characteristic of a substance that can only be observed during some type of chemical reaction.

Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

Summary. Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
40627
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

Which are physical, and which are chemical? Physical Properties: bluish color, pungent odor, gas at room temperature. Chemical Properties: very reactive, decomposes on exposure to ultraviolet light.

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.

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.
