This is a chemical property.Ĭhemical change results in one or more substances of entirely different composition from the original substances. Zinc reacts with hydrochloric acid to produce hydrogen gas.

Metals in general have they chemical property of reacting with an acid. For example hydrogen has the potential to ignite and explode given the right conditions. At this time this is very difficult to do and you are not expected to be able to do it. Eventually you should be able to look at the formula of a compound and state some chemical property. It is quite difficult to define a chemical property without using the word 'change'. What elements, electrons, and bonding are present to give the potential for chemical change.

volume: How much space the sample takes upĬhemical properties of matter describes its 'potential' to undergo some chemical change or reaction by virtue of its composition.

malleability: if a substance can be flattenedĮxtensive Properties: A physical property that will change if the amount of matter changes.

conductivity: electricity to flow through the substance.

Intensive properties: A physical property that will be the same regardless of the amount of matter. The property is proportional to the amount of material in the system. In contrast, an extensive property is additive for independent, non-interacting subsystems. When a diamond is cut, the pieces maintain their intrinsic hardness (until their size reaches a few atoms thick). Examples of intensive properties include temperature, refractive index, density, and hardness of an object. This classification relates to the dependency of the properties upon the size or extent of the system or object in question.Īn intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Physical properties of materials and systems are often described as intensive and extensive properties. Physical properties are used to observe and describe matter. Physical properties can be observed or measured without changing the composition of matter. It must display the two properties of mass and volume. Matter can be defined or described as anything that takes up space, and it is composed of miniscule particles called atoms. We are all surrounded by matter on a daily basis.
