What are the physical characteristics of a substance?

What are the physical characteristics of a substance?

Physical properties are characteristics that can be observed without changing the identity of the substance. Examples are shape, mass, color, volume and texture. Other physical properties can be measured such as melting point, boiling point, strength, hardness and magnetism.

What describes the characteristics of a substance?

The characteristic properties of a substance are always the same whether the sample being observed is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, viscosity, and solubility.

What are the physical properties of solution?

Colligative properties include vapor pressure, boiling point, freezing point, and osmotic pressure. The addition of a nonvolatile solute (one without a measurable vapor pressure) decreases the vapor pressure of the solvent.

What are chemical and physical properties?

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.

Which of the following physical characteristics is the same for a particular substance regardless of the sample size?

Because the density of a particular substance (something with a defined composition, such as pure copper), is the same for all pieces of that substance, regardless of size, density is often useful in determining the identity of a particular object.

What are the chemical characteristics of substance?

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.

What is physical solution?

A solution is defined as a chemically and physically homogeneous mixture of two or more substances. Homogeneous is a term used to imply that a mixture is uniform; that is, all the parts are identical. When subjected to routine chemical and physical analysis, the parts test the same.

What is physical chemistry of solution?

Solution, in chemistry, a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible.

What are the physical properties in chemistry?

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.

What characteristic of a substance is considered a chemical property?

What is the characteristics that describes a sample of matter?

Physical properties are characteristics that describe matter. They include characteristics such as size, shape, color, and mass. Chemical properties are characteristics that describe how matter changes its chemical structure or composition.

How are characteristic chemical and physical properties alike and how are they different?

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.
