how are physical and chemical properties similar and different?

Physical & Chemical Properties. Physical properties are those that can be observed without changing the identity of the substance. ... Properties that describe how a substance changes into a completely different substance are called chemical properties.

We learned that physical properties are things like shininess, conduction of heat or electricity, melting point, and density. Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction.

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).

These physical properties can be physical state, magnetic and electrical properties, specific gravity, density, melting point, boiling point and solubility. Here are some of the different methods of separating mixtures. Different compounds have different amounts of solubility at a specific temperature.

Physical versus chemical Sometimes it can be useful to distinguish between different types of properties. 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 are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. ... Flammability and corrosion/oxidation resistance are examples of chemical properties.

Examples range from the odor of a compound to its color. Two very common physical properties of organic compounds are boiling point and solubility. Solubility is the ability to dissolve a substance in a solution. Another physical property is density, which is defined as the mass per unit volume for a substance.

Physical properties are things that are measurable. Those are things like density, melting point, conductivity, coefficient of expansion, etc. Mechanical properties are how the metal performs when different forces are applied to them. That includes things like strength, ductility, wear resistance, etc.

Physical properties can be extensive or intensive. ... Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature.

Reactivity is surely a chemical property as it is determined by the valence electrons of a substance. Secondly, always a chemical change determines physical change in the substance. So if chemical properties of a substance is changed then surely its physical properties will have some or the other change.

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.
213446
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.

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.
808512
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
1020874
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.

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.

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.
