A thin stream of water is pulled to a statically charged balloon. Might a small ice cube also be pulled to a statically charged balloon?
A) No, this behavior is unique to water while in it liquid state only.
B) Yes, the same forces that cause the attraction in the liquid state are present in the solid state of water as well.
C) Yes and No. While the ice remains completely solid, no attraction occurs. Once the ice begins to melt so that both phases are present, the attraction becomes apparent.
D) Yes and No. Like the thin stream of water, the ice must be in motion in order for the attraction to be observed.
