11. the amount of matter in an object
mass
the amount of matter in an object
measured in grams

12. the amount of space an object takes up
volume
the amount of space an object takes up
measured in gallons, quarts, pints, liters, mL, and cubic inches, cubic cm, etc.

13. the amount of matter in a certain amount of space
density
the amount of matter in a certain amount of space
density = mass/volume

14. physical property
an attribute, or characteristic that can be observed and measured without changing what the matter is
