S4. Consider the conversation between two students about why the water level rises when a person sits down in a bathtub filled with water. I think that the water level rises in the bathtub because of mass. I think a 70 kg person will I disagree. The water level rises in the bathtub displace the same amount of water as any because of volume that is under the water-the space that a person occupies is the only factor, object with the same mass. it doesn't matter what the mass is. Kristen Daryl PC-102 Imagine that you were a third member of their group. Describe simple experiments (using only a graduated cylinder, an electronic balance, and a few blocks) that would provide evidence to contradict one idea and support the other. What would you expect to observe in your simple experiment? S5. While hiking, a student discovers a shiny, silver-looking piece of metal To determine if the metal is actually silver, the student decides to determine its density. In the lab, the student discovers the metal has a mass of 340 grams and a volume of 15.8 mL. Use the student's data and the data in the density table below to answer the student's question: is this piece of metal actually silver? Densities of Common Substances Substance Density (g/mL) Aluminum 2.70 Brass 8.40 Platinum 21.50 Lead 11.30 Silver 10.40 Gold 19.30 Iron 7.80
