  1. Volume and Density

  2. Volume (Capacity) • Volume is the amount of space taken up by an object. • Volume can also mean how much something holds. • Volume can be measured by multiplying LxWxH. • Volume can also be calculated by using water displacement.

  43. Density • Density refers to “how crowded” something is. The amount of matter within a certain volume. • Density can be measured in grams per milliliter (g/ml). • Solids are the densest phase of matter. Gases are the least dense.

  44. What would take up more space? A kilogram of feathers…..or a kilogram of steel?

  47. How to Calculate Density • Regular Shaped Solids – measure mass, then determine the volume by using a the formula LxWxH. EX: cubes, cylinders, spheres, cones, etc.

  48. How to Calculate Density • Irregular Shaped Solids: Find the volume of the object. You can use water displacement for this. Let’s use the metal ball again. It’s volume was 9 ml.

  49. How to Calculate Density • Irregular Shapes: Find the volume of the object. You can use water displacement for this. Let’s use the metal ball again. It’s volume was 9 ml. • Now find the mass of the object. You can use a triple bean balance scale for this.

  50. How to Calculate Density • Irregular Shapes: Find the volume of the object. You can use water displacement for this. Let’s use the metal ball again. It’s volume was 9 ml. • Now find the mass of the object. You can use a triple bean balance scale for this. Mass = 54 g • Divide the mass by the volume! 54 g ÷ 9 ml = 6 g/ml
