1. A liquid compound is not heated by microwaves the way water is. What can you conclude about the nature of the compound's molecules?
2.A solid metal cylinder has a certain resistance. It is then heated and carefully stretched to form a longer, thinner cylinder. After it cools, will its resistance be
a. the same
b. greater than
c. less than what it was before?
Explain your choice.
maybe the liquid compound is ionic. I think that water is covalent, and it gets heated up by "rattling" the molecules around in a microw. welll, second could have something to do with resistivity. I think i'd guess at b.
