1. Measuring Volume

2. What is Volume ??

3. Real Life Volume • Where do we see volume everyday

5. kL Metric Units cL mL L Volume is the amount of space an object takes up. The base unit of volume in the metric system in the liter and is represented by L or l. Metric Units 1 liter (L) = 1000 milliliters (mL) Which is larger? A. 1 liter or 1500 milliliters B. 200 milliliters or 1.2 liters C. 12 cm3 or 1.2 milliliters*

6. 9 cm 8 cm 10 cm Measuring Solid Volume We can measure the volume of regular object using the formula length x width x height. _____ X _____ X _____ = _____

8. What causes the meniscus? A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides. Measuring Volume We will be using graduated cylinders to find the volume of liquids and other objects. Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water. What is the volume of water in the cylinder? _____mL

9. Displacement • What happens when you have a container of water and you put an object into the water? • When an object is submerged in water, the water level in the container either rises or perhaps even spills over the side. This is called displacement. Water is displaced by the object.

10. Finding volume of an object using displacement • We can find the volume of an object by submerging it in water. • An object displaces exactly its own volume. • We can work out the volume of an object by watching the rise of the water level. If the container is filled to the top, we can measure how much water spills out. • V2- V1 or sometimes written as VF minusVI • V1 is the Initial Volume and V2 is the Final Volume.

12. The relationship • Displacement shows an interesting relationship between water milliliters (mL), cubic centimeters (cm3) and grams (g). • One milliliter (mL) of water takes up 1 cubic centimeter (cm3) and has a mass of 1 gram (g).
