Is The Change Of Color Physical Or Chemical

Main Difference – Physical vs Chemic Properties

Backdrop of affair can be divided into ii broad categories every bit chemic backdrop and physical backdrop. If the chemical composition of a substance is changed when a item property is changed, then that belongings is a chemical belongings. Simply if the changes of a holding practise not change the chemical composition of the substance, then that property is a physical holding. The main difference between physical and chemical properties is that concrete backdrop tin be observed without changing the chemical limerick of a substance whereas chemical properties can be observed past changing the chemical limerick of a substance.

What are Physical Properties

Physical backdrop are properties that can be measured without changing the chemical composition of matter. These backdrop can be used to draw the appearance and dimensions of matter. These concrete properties tin also exist used to detect and compare different forms of matter.

Physical properties can be found mainly in two types as intensive properties and extensive properties. Intensive properties are physical properties that practice not depend on the amount of substance. Extensive properties depend on the corporeality of substance. This means extensive properties change when the amount of the substance is inverse.

Properties regarding the appearance of substance are intensive properties. For case, colour is an intensive property. Melting point and boiling point of a substance are fixed (measured as standard values) values that depend but on the blazon of substance, not on the corporeality of substance. Density is also an intensive property that does not depend on the amount of substance considering it is determined as the mass of a unit of measurement volume.

Extensive backdrop depend on the amount of substance that is being considered. These properties modify when the amount of matter is inverse. For example, mass is a physical belongings because it is measured without altering the chemical composition of a substance. Mass is an extensive property since it is a measure of the amount of substance. As well, book, length or other dimensions that are changed when the corporeality of matter is changed are considered as extensive properties.

What are Chemical Backdrop

Chemical properties are properties that can be measured by changing the chemical limerick of a substance. The chemical composition of a substance is like the identity of that substance; if the chemical composition is changed, the substance becomes a different substance. Chemical properties mensurate the chemical changes that a substance may undergo when it is subjected to a chemic reaction. Therefore, the construction of the sample must be contradistinct for the chemical properties to become credible.

Chemical properties of matter tin can exist determined by observing the reactions of substances towards acids, bases, water or other chemicals. For instance, if a particular substance tin react with an oxidizing agent or a reducing agent, then the oxidation state of the elements in that substance is changed. Hence oxidation land is a chemical belongings. Likewise, there are many other chemic properties such every bit reactivity of elements, electronegativity, coordination number, enthalpy of combustion, etc.

Chemical properties of a substance have a strong relationship with the chemical bonds present in that substance. In club to change the identity of a substance, we have to either form new chemical bonds or break down existing chemical bonds. Therefore, observing chemical backdrop will always include free energy exchanges between the substance and the surrounding.

Difference Betwixt Physical and Chemical Properties

Definition

Physical Properties: Physical backdrop are backdrop that tin be measured without irresolute the chemical composition of matter.

Chemical Backdrop: Chemical properties are properties that can exist measured past irresolute the chemical composition of a substance.

Chemical Composition

Physical Properties: Concrete properties can exist measured without changing the identity of a substance.

Chemic Properties: Chemical properties are measured by irresolute the identity of a substance.

Chemic Bonds

Physical Backdrop: Physical backdrop do not have a direct relationship to the chemical bonds of a substance.

Chemical Properties: Chemical properties accept a direct relationship to chemic bonds.

Amount of Substance

Physical Properties: The physical properties may or may not depend on the corporeality of the substance.

Chemic Properties: The chemical properties practice not depend on the amount of the substance.

Examples

Physical Properties: Examples for concrete properties include mass, density, colour, book, etc.

Chemical Backdrop: Examples for chemical properties include reactivity of chemicals, oxidation country, coordination number, etc.

Conclusion

Physical and chemical properties of substances are very important in identifying and studying chemic compounds. Concrete properties are dissimilar from chemical backdrop of a substance. The main deviation between physical and chemical properties is that physical properties can be observed without changing the chemic composition of a substance whereas chemical properties tin can be observed by changing the chemical composition of a substance.
