Textbook Question
Chapter 18, Problem 18.94QP
Shown here is a galvanic cell connected to an electrolytic cell. Label the electrodes (anodes and cathodes) and show the movement of electrons along the wires and cations and anions in solution. For simplicity, the salt bridge is not shown for the galvanic cell.

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."
