Most of the substances that we see around have certain characteristics and properties by which they can be classified or identified. As such, substances are usually classified based on their chemical and physical properties. While chemical and physical properties are very important in studying substances, students should clearly understand the concept and also learn what is the difference between chemical and physical properties.
Chemical property refers to the property of a substance that can be observed or measured when the substance undergoes a chemical change. Chemical property can be observed by performing a chemical reaction. When a chemical change happens the molecular structure of a substance changes.
Anything that can be measured without changing the identity or chemical composition of the substance is known as the physical property of a substance. A physical change involves the formation of a new arrangement of matter but the structure of the atoms and molecules remains the same.
Chemical properties are totally different from physical properties in a lot of ways. Here we will look at some important differences between chemical and physical properties.
| Chemical | Physical |
| Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change. | Physical properties are properties that can be observed without bringing a chemical change. |
| A chemical reaction needs to be conducted to show the property. | No chemical reaction is needed here. |
| Chemical properties are connected to the chemical bonds of a substance. | Physical properties do not have such a relationship. |
| It can be used to predict how substances react. | It is mostly used in identifying or describing the substance. |
| Chemical properties of a substance can include: Compressibility, radioactivity, toxicity, flammability, heat of combustion, reactivity between chemicals, etc. | Examples of physical properties include: Molecular weight, boiling point, melting point, freezing point, volume, mass, length, density texture, colour, odour, shape, solubility, etc. |
These are some differences between chemical and physical properties. To know more about the differences between other chemistry topics you can keep visiting BYJU’S or download our app for interesting content and learning experience.
