Secretive and wary, weasels are difficult to study in. nature, and many gaps remain in our knowledge of their. reproduction. Two of the species covered in this Wild-. life Note (the ermine and the long-tailed weasel) exhibit.
Extensive - Properties that do depend on the amount of matter present. Mass - A measurement of the amount of matter in a object (grams). Weight - A measurement of the gravitational force of attraction of the earth acting on an object. Volume - A measurement of the amount of space a substance occupies. Length.
1 Density is a characteristic property of a substance. 2  The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). 3  The mass of atoms, their size, and how they are arranged determine the density of a substance.int: The size, mass, and arrangement of molecules affect the density of a substance. There are several possible answers for why sample B is more dense than sample A. 1  Sample B atoms might have more mass than Sample A atoms.
