- 1. Multiple Choice
A insect like a water strider can skate along the top of a pond, and aluminum can float on water because:
covalent bonds result in water cohesion
hydrogen bonds result in surface tension
low surface tension of water
- 2. Multiple ChoiceWhat word describes when water is attracted to other substances?cohesionadhesioncapillary actionsurface tension
- 3. Multiple ChoiceAttractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are calledCovalent bondsIonic bondsPolar bondsHydrogen bonds
- 4. Multiple Choice
Water travels up from the roots of a tree to the top because of
capillary action due to adhesion and cohesion
surface tension due to hydrogen bonding
high specific heat capacity
density of water compared to ice
- 5. Multiple ChoiceWater droplets take a spherical shape (as pictured) because of ____________adhesioncohesioncapillary actionsolubility
- 6. Multiple Choice
As you add drops of water to the surface of a coin, each drop sticks to the other water droplet because of ________________, and sticks to the penny because of ______________.
adhesion, cohesion
cohesion, adhesion

- 7. Multiple ChoiceWhich end of the water molecule has a slightly positive charge?the oxygen endthe hydrogen endboth ends are slightly positiveneither end is positive
- 8. Multiple ChoiceWater is a universal solvent because it...It can be found anywhereIt freezes when it gets coldfloats when frozenDissolves most substances
- 9. Multiple ChoiceIce floats when placed in a liquid water because:ice is less dense than the liquidice is more dense than the liquidice is solublewater is adhesive
- 10. Multiple ChoiceWhich of the following is LEAST likely to dissolve in water?nonpolar fats and oilspolar sugar moleculessalt made of a positive sodium ion and a negative chloride ionall of the substances will dissolve easily in water
- 11. Multiple ChoiceWhich statement best describes an effect of the low density of frozen water in a lake?When water freezes, it contracts, decreasing the water level in a lake.Water in a lake freezes from the bottom up, killing most aquatic organisms.When water in a lake freezes, it floats, providing insulation for organisms below.Water removes thermal energy from the land around a lake, causing the lake to freeze.
- 12. Multiple ChoiceWater, with nothing dissolved in it, will freeze at what temperature?0° C32° C100 ° C115 ° C
- 13. Multiple ChoiceWhich end of the water molecule has a slightly positive charge?the oxygen endthe hydrogen endboth ends are slightly positiveneither end is positive
- 14. Multiple ChoiceWhen a molecule has an opposite electrical charge on each end, it is known as what?cohesionpolar moleculehydrogen bondsolution
- 15. Multiple ChoiceWhy does ice float?As water freezes, it expands and its density decreases.As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.As water freezes, air becomes trapped between the hydrogen bonds of water molecules.As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
- 16. Multiple ChoiceA measure of the amount of solute in a given amount of solvent or solution is...saturatedsolubilityconcentrationmiscible
- 17. Multiple ChoiceA saturated solution is one that....contains the maximum amount of dissolved solute.contains less solute than a saturated solution.contains more solute than a saturated solution.is the amount of a substance required to form a saturated solution.
- 18. Multiple ChoiceAn unsaturated solution is one that....contains the maximum amount of dissolved solute.contains less solute than a saturated solution.contains more solute than a saturated solution.is the amount of a substance required to form a saturated solution.
- 19. Multiple ChoiceThe dissolving medium in a solution is called ...colloidsolutionsolutesolvent
- 20. Multiple ChoiceThe substance dissolved in a solution is called ...colloidsolutionsolutesolvent
