Pre$-$Lab Questions

Name

a$.$ Use the graph to calculate the slope of the line. Show work below. Hint: You can add points along the best$-$fit line and use those in your calculations instead of the given points. Include proper units!

b$.$ What physical property does the slope represent?

Define boiling point. Why is it important to add a boiling stone before measuring the boiling point?

Describe "supercooling" as it pertains to freezing point.

Would you expect hexane $(C_6{H}_{14})$ to be soluble in water? Explain.

What would you expect to have a higher boiling point, pentane $(C_5{H}_{12})$ or methanol $(C{H}_{3}OH)?$ Explain. $($Hint: think about the intermolecular forces for each molecule and compare their strengths$)$
