physical property is defined as a characteristic of matter that may be observed and measured without changing the chemical identity of a sample. The measurement of a physical property may change the arrangement of matter in a sample, but not the structure of its molecules. In other words, a physical property may involve a physical change, but not a chemical change. If a chemical change or reaction occurs, the observed characteristics are chemical properties. Any property you can see, smell, touch, hear or otherwise detect and measure without performing a chemical reaction is a physical property. Examples of physical properties include: color shape volume density temperature boiling point viscosity pressure solubility |
