TEACHER RESOURCE PAGE 13. Answers will vary. Sample answer: If the two substances are liquids, you could observe how they separate into layers as a result of differences in -density. If the two substances are solids, you could observe whether they float or sink in water. Density is a useful property for identifying substances because most substances have different densities that are constant at a given temperature and pressure. 14. Answers will vary. Sample answer: The astronauts should be able to carry more mass on the moon because the gravitational force acting on the objects is less there. Thus, the equipment will weigh less than it does on Earth. 15. Answers will vary. Sample answer: No; even though it would be nearly impossible to put the wood chips back together, this is still a physical change. The chips, log, and stump keep their identity as wood. Only their size and shape changes. 16. Mass is a measure of the amount of matter, while weight is a measure of gravitational force. Mass is constant no matter where the object is located while weight depends on where it is found in space. Mass is measured with a balance and expressed in grams, while weight is measured with a spring scale and measured in newtons. People tend to confuse the two concepts because both mass and weight remain constant on Earth, and weight does give you a fairly good estimate of the mass of an object. 17. The purple liquid will form the bottom layer, followed by the water and the red liquid. The yellow liquid will be on top. The greater the density, the lower the layer. Water has a density of 1.00 g/cm 3, which means it will float on the liquid with a density of 1.62 g/cm 3. The wood chip should sink through the yellow liquid and float on the red. 18. Step A involves a chemical change because the leaves turn brown. The color change signals a chemical change. 19. The salt did not burn, which shows that it has the chemical property of nonflammability. It has the physical property of solubility in water as well. Chapter Test C 1. D 12. C 2. D 13. volume 3.
