Textbook Question
Chapter 13, Problem 6RQ
The Volcanic Explosivity Index (VEI) is based primarily on the amount of material ejected from a volcano, although other factors play a role as well, such as height of plume in the atmosphere. The following table shows the number of volcanic eruptions (N) over the past 10,000 years having a VEI of between 2 and 7.
There are also VEI values of 0, 1, and 8. There is a level 0 volcano erupting somewhere on the Earth essentially all the time. There are one or more level 1 volcanoes essentially every day. The last known level 8 volcano was about 26 000 years ago
- a. Show the resulting data trendline, with equation and R2 value, on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear
- b. How many level 1 volcanoes does the model predict should have occurred in the last 10,000 years?
- c. How many level 8 volcanoes does the model predict should have occurred in the last 10,000 years?

Consider an introductory thermodynamics class experiment used to demonstrate phase change phenomena. A beaker of water is
heated, and its temperature measured over time to establish the temperature at which boiling occurs. The results, shown in the Figure
below, are for three separate tests conducted on different days by different student groups using the same equipment and method. Why
might the data from three seemingly identical tests show different results?
