Matters generally has two types of properties, these are intensive and extensive properties. An intensive property of a substance refers to that property that does not depend on the size or the quantity of that substance that is available. Another name for intensive properties is physical properties. These properties remain the same all the time no matter the quantity of the substance present. One example of intensive property is the density of water. No matter the quantity of water present or the location where you take the water sample from, the density of water will always be the same, that is, it is the same for every sample of water. Extensive properties on the other hand depend on the amount of that substance that is present. Examples are mass, weight, length and volume.
