Properties of Water

Surface tension also allows water to move through plant roots and stems and small blood vessels. As one molecule moves up the root or vessel, it pulls the others. This movement is referred to as ____________.

• Tension

• adhesion

• capillary action

• cohesion

Which state of matter requires the greatest amount of energy to change from the liquid state?

• solid

• gas

The temperature at which water changes phases from a solid to a liquid or a liquid to a solid.

• state temperature

• surface temperature

• freezing/melting point

• set point

Most liquids become denser as they cool. Water becomes less dense, because its molecules form an open _______ structure.

• star

• sublimination

• crystalline

• solubility
