Question

properties of matter can be determined without changing composition, while —— properties of matter must change the composition of matter. o chemical; physical o chemical; flammable o physical; metal o physical; chemical

Explanation:

Physical properties of matter can be observed or measured without changing the composition of the matter. Chemical properties involve a change in the composition of matter. Flammability is a chemical property as it involves a chemical reaction (burning). Metal - related properties like conductivity are physical properties.
