As an ice cube floating in a glass of water melts, what happens to the water level?
A) The water level rises to the point where the ice floats above the water.
B) As the ice melts, the water level does not changethe melting ice caves in and exactly fills the open spaces.
C) The melting ice caves in and fills the open spaces-therefore the water level is lower after the ice melts.
Question 2
How does the combined volume of the billions and billions of hexagonal open spaces in the structures of ice crystals in a piece of ice compare to the portion of ice that floats above the water line?
A) They are the same.
B) The volume of the open spaces is greater than the volume that extends above water.
C) The volume of the open space is less than the volume that extends above water.
D) The volumes are not related to each other.
