Why is ice able to float on water while other solids cannot float on
their liquid forms?
A) The orientation of hydrogen bonds pushes molecules closer together,
making ice denser than water.
B) The kinetic energy in other solids increases with temperature, making
them denser than ice.
C) The orientation of hydrogen bonds pushes molecules farther apart,
making ice less dense than water.
D) The molecules in other solids are packed less tightly, making them
denser than ice.
