Water properties

When water molecules stick to each other, it is called_________________

• cohesion

• adhesion

• polarity

• molecules

What property of water helps to moderate Earths temperature?

• specific heat capacity

• hydrogen bonds

• as water freezes, it expands and its density decreases

• capillarity

The hydrogen molecules have a slightly _____________ charge

• positive

• negative

• neutral

• small

What is polar molecule?

• in which one element pulls on the shared electrons more than the other element in a bond

• when water is really dense

• when water freezes and turns into ice

• when ice turns in to water vapor

What is suface tension?

• uneven forces acting on particles of the liquids surface

• a substance that dissolves other substances

• the force between two substances

• attraction between different liquid molecules

Hydrogen Bond

• Attraction between a slightly positive hydrogen atom and a slightly negative atom. This bond occurs between two water molecules.

• The process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

• The process of turning from liquid into vapor.

• The ability to dissolve many different solutes

Specific heat capacity

• The amount of energy required to change a substance's temperature

• Downward movement of water through soil into groundwater.

• Rain, snow, sleet, or hail that falls to the ground.

• The change of a substance from a liquid to a gas

The oxygen molecule has a slightly _________________ charge

• positive

• neutral

• negative

• opposite

cohesion

• attraction between molecules of the same substance; water molecules attract each other like little magnets.

• a weak interaction involving a hydrogen atom and a fluorine, oxygen, or nitrogen atom

• small pores in soil particles

• closely packed together; thick

Adhesion

• An attraction between molecules of different substances

• Attraction between molecules of the same substance

• Anything that has mass and takes up space

• a positively charged ion (H+) formed of a hydrogen atom that has lost its electron
