ACAP Science Review

An element and an atom are different but related because...

• A particular element is made up of many different types of atoms

• A molecule is the same as an atom

• An element is made up of all the same type of atom

• An element is smaller than an atom

If two objects have the same volume but one has a greater mass, the one with greater mass...

• Has a lower density

• Has a higher density

• Will float

• Will sink

If you cut a wooden block in half, each half would have...

• Half the density of the original piece

• Twice the density of the original piece

• The same density as the original piece

• No density at all

Density is a characteristic property of a substance. This means that the density of water

• Stays the same regardless of the volume

• Changes depending on the volume

• Is greater for a greater amount of water

• Is less for a smaller amount of water
