Water expands as it freezes because the hydrogen bonds in iceMultiple choice question.constantly form and re-form.are doubled between adjacent oxygen atoms.are broken.are stable and "lock" molecules into a more widely-space array.

One special physical property of water is that when water becomes solid(ice), it expands because the volume increases and the density:Question 6Select one:A.Increases and it floats in waterB.Decreases and it floats in waterC.Increases and it sinks in waterD.Decreases and it sinks in water

In an ice crystal, each water molecule is hydrogen bonded to …………..neighbouring molecules.

What happens to water when it changes to ice? Its density increases. Its density decreases. Its mass increases. Its mass decreases. Its volume increases. Its volume decreases.

When ice melts its particlesgain energy and begin to movecome close together and lose energy.lose energy and begin to move.move very far apart and gain energy

What happens to ice as it melts?A.The average kinetic energy of the water molecules increases.B.The absorbed energy breaks apart intermolecular forces.C.The released energy increases the intermolecular forces.D.The average kinetic energy of the water molecules decreases.
