How to use chemical property in a sentence
Atoms are the smallest particles with distinct chemical properties.
They can exist on their own — cellulose is a plant glycan made up of long chains of glucose — or they can be anchored to other biomolecules like proteins and lipids, whose chemical properties they modify.

A molecule is the smallest particle of a substance that still has all the chemical properties of that substance.
Corrosionpedia Explains Physical Properties
Physical properties are studied alongside chemical properties in order to determine the way in which a material behaves in a chemical reaction.
A given element may have different physical properties in different phases or in different compounds.
Classifications for Physical Properties
There are two classes of physical properties:
- An extensive property depends on the sample’s size. Examples of extensive properties are variables such as shape, volume and mass.
- An intensive property, on the other hand, is one that does not depend on the size or amount of matter in a sample. It is a constant characteristic of the material regardless of how much matter is present. Examples of intensive properties are the melting point and density.
These classifications are usually only valid in those cases where a smaller subdivisions of the sample does not interact when combined in some physical or chemical process.
Physical properties are also classified with respect to the directionality of their nature. For example, isotropic properties do not change with the direction of observation, while anisotropic properties have spatial variance.
Supervenient Properties
It can be difficult to determine if a given property is a physical property or not. Color, for instance, can be seen and measured; however, color itself is really an interpretation of the reflective properties seen in a surface and the light that is used to illuminate it. For this reason, many ostensibly physical properties are called supervenient.
A supervenient property refers to one that is actual but is secondary to some underlying reality.
This is like the way in which objects are adscititious on the atomic structure.
For instance, a pencil may have the physical properties of mass, shape, color, temperature and so forth, but these properties are supervenient on the underlying atomic structure, which may in turn be supervenient on an underlying quantum structure.
What Is Property?
Property is a term describing anything that a person or a business has legal title over, affording owners certain enforceable rights over said items.
Examples of property, which may be tangible or intangible, include automotive vehicles,
But properties can simultaneously be liabilities in some situations. Case in point: if a customer sustains an injury on a company’s property, the business owner may be legally responsible for paying the injured party’s medical bills.
Evaluating Property Assets
When auditors, appraisers, and analysts calculate the value of a business, they factor all of its underlying property into the equation. For example, a manufacturer of small machine parts may gross just $80,000 per year, but if it owns the factory in which it operates, and that building is appraised at $1 million, the overall value of the business would be substantially higher than profits alone suggest. Furthermore, if that same company holds a patent for a part, it has the potential to generate substantial income by licensing the rights to manufacture that item to a larger business, rather then producing the part in-house. In this way, licensing deals may create lucrative revenue streams that significantly boost a company’s overall value.
What are the 5 properties in science?
- color (intensive)
- density (intensive)
- volume (extensive)
- mass (extensive)
- boiling point (intensive): the temperature at which a substance boils.
- melting point (intensive): the temperature at which a substance melts.

What is the properties of matter and example?
The properties of matter include any traits that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.
What are the properties of substances?
Some of the physical properties of substances include their:
- Changing states without altering or changing the identity of the substance.
- Mass.
- Density.
- Volume.
- Boiling point.
- Melting point.
- Conductivity.
- Heat capacity.
Intensive and Extensive Physical Properties
The two classes of physical properties are intensive and extensive properties:
- An intensive property does not depend on the amount of matter in a sample. It is a characteristic of the material regardless of how much matter is present. Examples of intensive properties include melting point and density.
- An extensive property, on the other hand, depends on sample size. Examples of extensive properties include shape, volume, and mass.
Matter can be identified through its properties.
One clue to helps us identify matter is magnetism.
Another property that can help us identify matter is solubility.
Acetone is a chemical found in nail polish remover. Acetone does a great job dissolving nail polish, but it cannot dissolve salt.
what does properties mean in science Density is an important property of matter.
To better understand density you can think about the difference between a golf ball and a ping-pong ball. Even though they are about the same size, golf balls are heavier because they have a higher density.
How something floats or sinks is also related to its density. The helium balloon went up because its density is less than air. The balloon with sulfur hexafluoride sank because its density is greater than air.
Skill development
Children will develop their working scientifically skills by:
- Asking their own questions about scientific phenomena.
- Selecting and planning the most appropriate ways to answer science questions, including:
- Finding things out using a wide range of secondary sources of information.
- Grouping and classifying things.
- Carrying out comparative and fair tests.
- Recording data and results using scientific diagrams and labels, classification keys, tables, scatter graphs, bar and line graphs.
- Drawing conclusions and raising further questions that could be investigated, based on their data and observations.
- Using appropriate scientific language and ideas to explain, evaluate and communicate their methods and findings.
