Classification and Properties of Matter In chemistry and physics, matter is any substance that has mass and takes up space by having quantity. However it does not embody massless particles corresponding to photons, or other power phenomena or waves such as light or sound. Matter exists in varied states which are outlined by numerous physical properties, corresponding to state of matter, part, shape, and density. On predicting merchandise, classifying reactions and balancing equations. The right answer, after all, is E. In chemistry, the mole is defined as an quantity of a substance that accommodates 6 × 1023 particles of that substance.
