  12. 12. Which do you think would have the greater volume? The greater mass? Why? 1 kg of feathers 1 kg of rocks
  13. 13. Properties of matter • HARDNESS • FRAGILITY • ELASTICITY • DENSITY
  14. 14. Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume. Density
