Chapter 11, Problem 60TE

Use exercise 58 as an analogy to describe what occurs in exercise 59. Does it make to think that the alcohol is made of very tiny particles (molecules) rather than being an infinitely continuous material?

Exercise 58: A skillet is lined with a thin layer of cooking oil followed by a layer of unpopped popcorn kernels. Upon heating the kernel, all pop, thereby escaping the skillet. Identify any physical or chemical changes.

Exercise 59: A cotton ball is dipped in alcohol is wiped across a tabletop. Would the resulting smell of alcohol be more or less noticeable if the tabletop were much warmer? Explain.
