![]() ![]() Physical properties can be measured by not changing the chemical composition of the matter.Ĭhemical properties are the characteristics of a substance that cannot be identified or determined by normal vision or by touching the substance. This proves that the physical property of a physical substance remains the same even after the testing or conversion to another state and changes can be converted to the previous state. ![]() Physical properties of a given element may differ from one phase to another but the structure of the molecule remains the same – for example, the state of water changes in solid, liquid, and gas to ice, water, and vapor respectively but these changes are reversible as vapor can be compressed to change its state to liquid (water), and the liquid (water) can be changed to solid (ice) but the chemical identity remains same in all the states i.e. For example, changing a copper plate to a copper wire is a physical change because the structure of the molecules here remains the same but the shape changes, and these changes are reversible. Testing a physical property or changing the shape of physical property may change the arrangement of the substance but not the structure of the molecules. The characteristics of physical properties can be measured and observed without. Examples of chemical properties are acidity, the heat of combustion, any type of reaction, toxicity, etc. A physical quantity is known as quantifiable physical properties.Ī chemical property is defined as characteristics of matter that change from one type to the other when tested and cannot be reversed back to the previous state again. A state of a physical system is described by the value of physical properties. Physical property is defined as characteristics of matter that are visible to our naked eyes and can be measured these characteristics are size, shapes, color, state of matter (liquid, gas, and solid), strength, mass, etc.
