Characteristics that identify a sample of matter as a substance are simply whether it is matter or not. However, which substance the matter is can be identified through its density, melting point, conductivity, etc...
Physical property is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. Some examples of physical properties are viscosity, conductivity, malleability, hardness, melting point, boiling point, and density.
"A sample of matter can be either a pure substance or a mixture. A pure substance has a fixed, characteristic composition an a fixed, definite set of properties. Pure substances are for example copper, salt, diamond, water, table sugar, oxygen, Mercury, vitamin C, and ozone. A pure substance may be a single element, such as copper or oxygen, or a compound of two or more elements in a fixed ratio, such as salt (39.34 % sodium and 60.66 % chlorine) or table sugar (42.11 % carbon, 6.48 % hydrogen, and 51.41 % oxygen). A mixture is a collection of pure substances simply mixed together. Its composition is variable, as are its properties. Examples of mixtures are milk, wood, concrete, saltwater, air, granite, motor oil, chocolate, and elephants." from: http://chemweb.ucc.ie/what_is_chemistry.htm
Thse are chemical composition, density, melting point - intensive properties.
weight, volume, density, mass
Temperature and amount of the substance do not change chemical properties.
Examples: density, hardness, boiling point, refractive index.
Sodium chloride is it an entirely different substance with its own unique properties.
Characteristic properties are unique for every different substance.
Every substance has certain properties that show things about them, such as odor, taste, malleability, hardness, color, state at room temperature, and melting/boiling point. If you know the color of a substance, it is far easier to determine what that substance is, and if you know the color and the boiling point, your choices are limited even further. Using the physical properties of a substance, you can identify the substance based off of its unique properties or combinations of properties.
A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
The main ingredients are Carbon Monoxide, Tar, and nicotine. However the properties of an unburned substance are different from a burned substance.
When a substance changes, any or all of its properties can also change.
Temperature and amount of the substance do not change chemical properties.
Examples: density, hardness, boiling point, refractive index.
The chemical properties of an object show what a chemical change did to that substance.
properties of matter that determine how a substance reacts with other substances
The physical properties of a substance are the substance's physical appearance. This includes the color, shape, weight, width, and height.
Firstly (and most importantly) the actual chemical makeup of the compounds in terms of the specific elements involved, and those elements respective properties. Secondly the temperature, pressure, etc. at which a substance is at will affect the properties of the substance. Thirdly what other chemical compounds are effecting the substance, obviously different substances will react differently depending on what are reactants are present.
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Sodium chloride is it an entirely different substance with its own unique properties.
Yes, these are thy physical properties of substances.
