How can properties of matter be used to classify matter?
The right answer probably depends on the way your teacher already explained the subject. It sounds like copper was already used as an example. Can you take what was done with copper and expand it or apply it to some other things? What part do you not understand? Break the question into pieces. Do you understand “properties?” It just means something that helps describe a thing. Properties of air would include being colorless, a gas, something you can squish, and so on. Properties of cheese include being solid, containing fat and protein, and being edible. Do you understand “matter?” I think so, it’s just anything that has mass (weight)–basically, any physical thing besides energy. Do you understand “classify?” It means organizing, breaking things up into groups so that you can understand them better. You can classify animals into things that live in the water, those that live on the land but don’t fly, and things that fly. Or you could classify them by what they eat: meat-eaters, plant
