chemical and physical properties

neither chemical nor physical properties

Only chemical properties change the composition of a substance,

Physical properties do not change composition. Physical properties have to do with the physical appearance of an object.

Chemical properties can be observed during a chemical reaction. For instance when paper is being burnt. Chemical changes are what causes a substance to change into a different substance entirely.
