Preparing for Chapter 2 Test

Turn to Page 55 and read the Chapter 2 summary.

On pages 56-57 you will find the Chapter 2 review, complete the review.

Check your answers with those in the Key Points.

Review the answers then print the results for your records.

2. meniscus
3. standard mass
4. weight
5. property
6. displacement of water
7. D
8. A
9. A
10. C
11. The information is not specific or exact enough; it does not include measurements.
12. Measure the mass of a graduated cylinder. Add the liquid to the cylinder and measure mass again. Subtract the cylinder's mass from the mass of the cylinder and liquid to get the liquid mass.
13. Cube: Multiply width by length by height in cm. This is also the number of mL, since 1mL = 1 cm3. Glass of water: Pour the liquid into a graduated cylinder and read the scale. Rock: use the displacement of water method. Pour water into a graduated cylinder and read its volume. Add the rock and read the scale again. Subtract water volume from total volume of water and rock.
14. The cork will float because it is less dense that water.
15. The scientist would measure each object's volume and mass and then calculate its density (mass/volume). If the densities are identical, the objects are the same substance.

Congratulations you finished the second chapter !!
