matter is anything that takes up space and can be described by physical and chemical properties. which statement best differentiates chemical properties from physical properties? a) physical properties are properties that can be physically seen or touched, while chemical properties can only be found when matter is mixed with specific chemicals. b) physical properties are measured when matter changes its physical state, while chemical properties can only be measured if matter remains in one state for an extended time. c) physical properties are difficult to measure because they require special tools to detect, and chemical properties are easy to measure and require not special tools to detect. d) physical properties can be measured/observed without changing matter into something else, while chemical properties describe matter's ability to react/combine with other matter.
