Water Changes by Brenda Parkes
A liquid takes the shape of any container it is poured into, but doesn't change its volume as it flows from one container to another. (Volume means the amount of something or the quantity of space it takes up.) A solid keeps its shape and volume. Water becomes a solid when temperatures drop below freezing. Water's freezing and melting points are not very extreme, so it can pass from phase to phase in the course of a day.
