Which order of letters ranks the samples by volume from largest to smallest? (1) A, B, C (3) C, B, A (2) A, C, B (4) C, A, B 2. What is the density of sample A? (1) 0.33 g/cm 3 (3) 3.0 g/cm 3 (2) 2.0 g/cm 3 (4) 4.0 g/cm 3 3. Which graph best represents the relationship between the mass and volume of the substance? Substances A, B, C, and D are at rest in a container of liquid as shown by the diagram. 4. What is the term used to describe the pull of gravity on an object? 1 mass 3 weight 2 volume 4 density 5. Which choice lists the substances in order of decreasing density? 1 A, B, C, D 2 A, D, C, B 3 D, C, B, A 4 C, B, A, D
2 Base your answers to questions 6-8 on your knowledge of Earth Science, the Earth Science Reference Tables, and the diagrams below. The diagrams represent three solid objects made of the same uniform material. The name of each shape is shown, along with its mass (M) and volume (V). 6. What is the actual length of any one side of the cube? (1) 1.0 cm (3) 3.0 cm (2) 2.0 cm (4) 4.0 cm 7. According to the graph, which line on the graph below best represents the density of the three samples? (1) A (2) B (3) C 8. Line A represents a different unknown substance. If you had a 3 cm 3 sample of this unknown substance, what would the mass of this sample be? (1) 5 grams (3) 15 grams (2) 10 grams (4) 20 grams 9. The mass of a solid is measured to be 76.5 grams. If the known density of the solid is 3.0 g/cm 3, what would be the volume of that solid? 10. The graph to the right shows the relationship between the mass and volume of a mineral. What is the density of this mineral? (1) 6.0 g/cm 3 (3) 3.0 g/cm 3 (2) 9.0 g/cm3 (4) 4.5 g/cm 3
3 Base your answers to questions on your knowledge of earth science, the Earth Science Reference Tables, and the diagrams below. Objects A and B are solid and made of the same uniform material. 11. If object B has a mass of 173 grams, what is its density? (1) 0.37 g/cm 3 (3) 3.7 g/cm 3 (2) 2.7 g/cm 3 (4) 5.7 g/cm A third object is made of the same uniform material as object B, but it is spherical in shape. How does the density of this third object compare to the density of object B? (1) It is one-half as dense as B. (3) It is the same density as B. (2) It is twice as dense as B. (4) It is four times as dense as B. 13. If substance B was placed in a bucket of water it would (1) float at the top (2) sink (3) remain suspended in the middle of the water halfway from the top and bottom 14. As elevation above sea level increases, an object s weight will (1) decrease because gravitational pull increases (2) decrease because gravitational pull decreases (3) increase because gravitational pull increases (4) remain the same 15. Which of the following definitions best describes the measurement of mass? (1) the amount of mass in a given volume (2) the amount of space an object takes up (3) the amount of gravitational pull on an object (4) the amount of matter in an object 16.
