Question

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.

Answer 1

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.

Answer 2

1. They are meant tot be eaten cold? Are there chocies for number one?
2. Greater/
