In science, properties refer to the qualities and characteristics of a substance that describe and identify it/01%3A_Introduction_-Matter_and_Measurement/1.03%3A_Properties_of_Matter). Properties can be used to describe matter by observation, measurement, or combination. There are two main types of properties in science: physical properties and chemical properties/01%3A_Introduction-_Matter_and_Measurement/1.03%3A_Properties_of_Matter).

Physical properties are those characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume/01%3A_Introduction_-_Matter_and_Measurement/1.03%3A_Properties_of_Matter). Density, color, hardness, melting and boiling points, and electrical conductivity are all examples of physical properties. Physical properties can be further classified as intensive or extensive properties. Intensive properties are those that do not depend on the amount of matter present, such as temperature and density. Extensive properties, on the other hand, depend on the amount of matter present, such as mass and volume.

Chemical properties, on the other hand, describe the characteristic ability of a substance to react to form new substances/01%3A_Introduction_-_Matter_and_Measurement/1.03%3A_Properties_of_Matter). Reactivity, flammability, and the ability to rust are among them. Chemical properties can only be measured or observed as matter transforms into a particular type of matter.

Scientists need to understand the properties of matter because it is made up of it. All samples of a pure substance have the same chemical and physical properties/01%3A_Introduction_-Matter_and_Measurement/1.03%3A_Properties_of_Matter). Physical changes are changes in which no chemical bonds are broken or formed, and the same types of compounds or elements that were there at the beginning of the change are there at the end of the change/01%3A_Introduction-_Matter_and_Measurement/1.03%3A_Properties_of_Matter).

In summary, properties in science refer to the qualities and characteristics of a substance that describe and identi...
