If a liquid sample of a given size is moved into a larger container, the liquid will NOT expand to fill the container completely although it may change its shape to conform to the container. What does this behavior imply about the attractive forces between liquid particles? A. Liquids have very strong attractive forces holding them together B. Liquids have moderately strong attractive forces holding them together C. Liquids have very weak attractive forces holding them together.
