what are the differences between chemical and physical properties?
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.

Chemical properties that are important in characterizing materials include composition, structure, molecular weight, boiling and melting points, vapor pressure, octanol-water partition coefficient, water-solubility, reactivity, and stability.

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.

physical property: Any characteristic that can be determined without changing the substance's chemical identity. chemical property: Any characteristic that can be determined only by changing a substance's molecular structure.

A chemical property is a characteristic of a substance that may be observed when it participates in a chemical reaction. Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.
589301
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.

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.

Chemical properties are characteristic properties of elements shown during chemical change. Chemical properties are properties of an element or compound that are seen during any chemical reactions.
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.
303969
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.

The difference between physical and chemical equilibrium is that a physical equilibrium is an equilibrium in which the physical state of the system does not change whereas chemical equilibrium is the equilibrium state in which the concentrations of reactants and products is not changed with time.

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.
307409
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed.

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.
1308478
All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. ... 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 and chemical properties. 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.
524707
Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. ... A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter).
