    A) False

    B) True

    Explanation:

    The question is incomplete. The complete question is as follows.

    There are two statements. Identify which statement is true or false.

    A) For any substance, solid, liquid or gas, mass increases as volume increases.

    B) Density represents mass per volume.

    Statement A

    Mass is defined as the amount of matter in an object. Its fixed and can't be changed. Volume on the other hand is the amount of space an object takes up.

    Since the amount of matter is fixed, an increase in volume doesn't cause an increase in mass. For example, a test tube, with a volume of 10ml, contains liquid fragrance. When heated, the fragrance vaporizes and fill the entire room, until you can smell it in every corner. Note that previously the fragrance of same mass was occupying a 10ml space in the test-tube. After heating, the same mass of fragrance occupied the entire room (volume increased but mass remained constant).

    It happened because as the fragrance is heated, the space between molecules increases causing them to occupy more space BUT in the whole scenarios, the number of molecules stayed unaffected. Hence statement A is false.

    Statement B

    Density measures the compactness of the substance. It's defined as the amount of mass per unit volume. It increases as the atoms/molecules in a substance comes closer. Density of solids are greatest as the atoms/molecules are tightly packed together. It is least in gases as the molecules are far apart from each other. Hence the statement is true.
