Answer to Question 1

ANS: T
Recall the example in the book about a candle and a bathtub. The candle flame has a higher
temperature, but the bath generates more heat. The quantity of molecules vibrating can greatly impact
the amount of heat produced. Information can be found in the section Water Has Unusual Thermal
Characteristics.

Answer to Question 2

ANS: T
The bending of light and sound waves is called refraction. When a light wave or a sound wave leaves a
medium of one densitysuch as airand enters a medium of a different densitysuch as waterat
an angle other than 90, it is bent from its original path. Information can be found in the section
Refraction Can Bend the Paths of Light and Sound through Water.
