All such physical properties are measurable or observable. The physical properties like color, melting point, boiling point, hardness, and malleability are observed without any chemical change in the matter. There are many differences between these chemical and physical properties of substances that will be highlighted in this article. Chemical properties of matter describe its potential to undergo some chemical change or reaction by virtue of its composition. Chemical properties are only observed during a chemical reaction and thus changing the substance's chemical composition. Some examples of chemical properties are – toxicity, the heat of combustion, reactivity, enthalpy of formation, oxidation states, radioactivity, etc. A physical property is an aspect of matter that can be observed or measured without changing its chemical composition. What is the difference between physical and chemical properties? The answer has to do with chemical and physical changes of matter. Some non-metals are solids and some are gases at room temperature. Main Differences Between Physical Properties and Chemical Properties. It is quite difficult to define a chemical property without using the word "change". Their physical and chemical properties vary widely. Physical properties describe characteristics of matter rather than change in composition due to chemical reaction. ... Have a look at the given table depicting the major differences between Metals And Non-metals for better understanding. In particular, these properties encompass texture, density, mass, melting and boiling points, and electrical and thermal conductivity. A chemical property may only be observed by changing the chemical identity or substance. Difference Between Physical Properties and Chemical Properties The elements, electrons, and bonds that are present give the matter potential for chemical change. Extensive properties, such as mass and volume, depend on the amount of matter being measured. A material’s physical properties denote the physical state of materials that are exclusive of their chemical or mechanical components. The above demarcation between metals, nonmetals, and metalloids may vary since the nature of some elements is still under research. The physical and chemical properties of metalloids lie intermediate between those of metals and nonmetals. Differences Between Metals And Non-metals. A chemical property is any property which gets determined when a change takes place in the chemical identity of the substance. Key Takeaways Key Points. Recognize the difference between physical and chemical, and intensive and extensive, properties. What is the difference between a chemical property and a physical property? A Physical Property. All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. Some important physical properties are electric conductivity, density, colour change and much more. Chemical Properties. Perhaps the best way to distinguish between the two is by examples.
