This mathematical model describes the changes that occur in a sample of
water as its temperature increases. Based on this model, how do you expect
the motion of the molecules in ice to compare with the motion of molecules
in water vapor?

O A. This model does not provide enough data to answer the question.
OB. I expect the molecules in water vapor to move more quickly than
the molecules in ice.
O C. I expect the molecules in ice to move more quickly than the
molecules in water vapor.
D. I expect the motion to be very similar.
