The boiling point is 176° F, and the freezing point is 42° F. Part A: Write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid. Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality represent. Part C: In February, the building's furnace broke and the temperature of the building fell to 20° F. Would the chemist have been able to conduct her research with benzene on this day? Why or why not?
