  1. The graph shows soap density data. Use the graphed data to answer the following questions.
    Soap density Soap density Dial Basic Neutrana Ivory volume (cm³) mass (g) y-axis labels 0 10 20 30 40 50 60 70 80 90 100 x-axis labels 0 10 20 30 40 50 60 70 80 90 100
    1. __________ _____ Calculate the density ρ of Dial Basic soap.
    2. ______________ Based on the density, will Dial Basic soap float or sink?
    3. __________ _____ Using the density above, calculate the mass of a bar of Dial Basic soap that has a volume of 100 cm³.
    4. __________ _____ Using the density above, calculate the volume of a bar of Dial Basic soap that has a mass of 250 grams.
    5. __________ _____ Calculate the density ρ of Ivory soap.
    6. ______________ Based on the density, will Ivory soap float or sink?
    7. __________ _____ Calculate the density ρ of Neutrana soap.
    8. ______________ Critical thinking: Based on the density, will Neutrana soap float or sink?

    1. Plot the soap data on the graph.
    2. __________ __________ Calculate the density of the soap. Include the units with your answer.
    3. ______________ Based on the slope, will this soap [float] OR [sink]?
    4. ______________ Based on the slope, is this soap likely to be [Ivory] OR [Dial] soap?
    5. __________ __________ Calculate the mass for this soap for a volume of 200 cm³.
    6. __________ __________ Calculate the volume for this soap for a mass of 240 g.
  3. Critical thinking: Some laboratory groups obtained slopes which incorrectly predicted whether their soap would float or sink. Which are they more likely to have measured incorrectly and WHY: the volume or the mass?
  4. For the following RipStik velocity chart:

    1. __________ _____ Determine the velocity ѵ of the RipStik.
    2. __________ _____ If the RipStik continued at that velocity for 30 seconds, how many centimeters would the RipStik travel?
    3. __________ _____ If the RipStik continued at that velocity for 5700 centimeters, how many seconds would the RipStik travel?
  5. A RipStik moved at three different velocities (speeds). The data was gathered in the tables and plotted on the graph seen below.
