Physical Science Study Guide 8th Grade
Physical properties are traits that you can observe without changing the identity of a substance, like boiling point, color, malleability, or solubility. All of these can be observed without changing the molecular makeup of the substance. A chemical property can only be observed by changing the substance into something new; flammability can only be observed by setting something on fire, and reactivity can be observed by observing rust form.
