Item AM033003: Ice is harder than liquid water because the molecules of ice are linked more tightly together than the molecules of liquid water.
Why is ice harder than liquid water?
- The molecules of ice are not moving.
- The molecules of ice are linked more tightly together.
- The molecules of ice are harder than the molecules of liquid water.
- The molecules of ice are made of solid atoms, and the molecules of liquid water are made of liquid atoms.
