Question
Chapter 1, Problem 14P
Interpretation Introduction
Interpretation: The risk-benefit analysis on the use of sodium sulfite as a preservative in fruit juices, wines etc.should be done.
Concept Introduction: Risk benefit analysis is a process by which the pro and cons of designing a product is evaluated. Every product will incur a certain risk and a certain benefit. It is advisable to make a product only when the benefits outweigh the risks of making the product.

Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know?
(see page 276 text) the design of the beaker is a uniform cylinder
the volume of liquid increases evenly with its height
resulting in a linear relationship.
What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the
graph to assist you in answering the question.
4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a
best-fit curve through the points and label it "250 mL Florence flask."
