3. Metric System Part 3 Volume

4. What is Volume ? Volume is a measure of how much space something takes up

5. 3 Methods of Measuring Volume

6. Measure the volume of a liquid directly using glassware Method # 1:

7. Meniscus Definition: the curved surface of liquid in a container

9. Practice: 53 mL

10. Practice: 11.5 mL

11. Practice: 6.6 mL

12. Method # 2: Calculate the volume of a regularly shaped solid using geometry

13. Geometric Formulas: Volume of a cube is …. l x w x h i.e. 4cm x 5cm x 2cm = 40 cm 3 i.e.  x (5cm) 2 x 10cm = 785 cm 3 Volume of a cylinder is ….  r 2 h

14. NOTE : Volume can be measured in: liters (L), milliliters (mL), etc. cubic meters (m 3 ) cubic centimeters (cm 3 ), etc. OR…

15. It uses the decimal system (10’s!) It is an International Standard. The units relate to each other.* *(More on this later!) Benefits of the Metric System: Remember this slide?

16. The units relate…. 1 cm 3 = 1 mL 1 cm 3 = 1 mL 1 mL H 2 O 1 mL H 2 O = 1 cm 3 H 2 O = 1 g H 2 O using water as a standard:

17. Typically, mL or L are used to describe the volume of a liquid... …and cm 3 or m 3 are used to describe the volume of a regularly shaped solid.

18. Method # 3: Calculate the volume of an irregularly shaped solid using water displacement

19. Use water displacement to find the volume of objects with weird shapes:

20. Use Water Displacement to find the volume of an irregularly shaped solid, such as a rock: 22 ml 32 ml

21. A formula for water displacement: V = V f - V i Volume of Object = (Final Volume) - (Initial Volume)
