    well A and D it seems to be here.... @NayelliPm3 You are already familiar with the most common physical properties of matter. Some of these properties, such as mass and volume, depend upon the specific object in question. You cannot use mass to tell one substance from another because two very different objects can have the same mass—a kilogram of feathers has the same mass as a kilogram of peanut butter, for example. Other properties, such as density, can be used to identify substances. They do not vary from one sample of the same substance to another. For example, you could see a difference between a kilogram of liquid soap and a kilogram of honey by measuring their densities. The physical properties described below can be used to identify a substance. Density The densities of wood, plastic, and steel are all different. Scientists already have determined the densities of many substances. As a result, you can conveniently compare the density of an unknown substance with the densities of known substances. Finding any matching densities will give you information about the possible identity of the unknown substance. However, it is possible for two different substances to have the same density. In that case, in order to identify the substance positively, you would need additional data.
