Chemical properties can only be determined by changing a substance.
Chemical Properties
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Chemical and physical properties
Chemical properties are properties that describe chemical traits; for example, reactivity, acidity, and toxicity are all chemical traits; you may say they aren't obvious. A physical property describes a physical trait that has to do with state of being, and are for the mostpart obvious: state of matter, color, odor, shape, melting/freezing point, density, etc.
A property that describes a substance is a characteristic that can be observed or measured without changing its chemical identity. These properties can be classified as physical, such as color, melting point, and density, or chemical, such as reactivity and flammability. Understanding these properties helps in identifying and categorizing substances in chemistry and materials science.
