  1. 1Defining Density

    Density is an important [blank_start]physical[blank_end] property of matter. It reflects how [blank_start]closely[blank_end] packed the particles of matter are. When particles are packed together more tightly, matter has greater [blank_start]density[blank_end].
    1. Aphysical
    2. Bclosely
    3. Cdensity
  2. 2To better understand density, think about a bowling ball and volleyball, pictured in the Figure below. Imagine lifting each ball. The two balls are about the [blank_start]same[blank_end] size, but the bowling ball feels much [blank_start]heavier[blank_end] than the volleyball. That’s because the bowling ball is made of [blank_start]solid plastic[blank_end], which contains a lot of [blank_start]tightly packed[blank_end] particles of matter. The volleyball, in contrast, is full of [blank_start]air[blank_end], which contains fewer, more [blank_start]widely spaced[blank_end] particles of matter. In other words, the matter inside the bowling ball is [blank_start]denser[blank_end] than the matter inside the volleyball.
    1. Asame
    2. Bheavier
    3. Csolid plastic
    4. Dtightly packed
    5. Eair
    6. Fwidely spaced
    7. Gdenser
  3. 3The density of matter is actually the amount of [blank_start]matter[blank_end] in a given [blank_start]space[blank_end]. The amount of matter is measured by its [blank_start]mass[blank_end], and the space matter takes up is measured by its [blank_start]volume[blank_end]. Therefore, the density of matter can be calculated with this formula:

    Density=[blank_start]mass[blank_end] / [blank_start]volume[blank_end]
    1. Amatter
    2. Bspace
    3. Cmass
    4. Dvolume
    5. Emass
    6. Fvolume
  4. 4What is the density of a liquid that has a volume of 30 mL and a mass of 300 g?

    A: The density of the liquid is:

    Mass =[blank_start]300[blank_end] g
    Volume =[blank_start]10[blank_end] mL
    Density = [blank_start]30[blank_end] g/ml
    1. A300
    2. B30
    3. C10
