- 1. Multiple ChoiceLarge bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?Water is an acid.Water is a versatile solvent.Water has a high heat capacity.Water acts as a buffer.
- 2. Multiple ChoiceWhy does ice stay at the top of oceans instead of sinking to the bottom?Ice is colder than liquid water.Ice is less dense than liquid water.Ice is more dense than liquid water.Ice is warmer than liquid water.
- 3. Multiple Choice
Water is often called the "universal solvent" because many substances can be dissolved in water. What property of water allows it to be such a versatile solvent?
purity
polarity
high heat capacity
expansion upon freezing
- 4. Multiple ChoiceSmall insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?The insects are light enough so that they do not break the hydrogen bonds holding the water molecules togetherThe insects actually use their wings to hover slightly above the water's surface and they only skim it with their feetThe insects' feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water's surfaceThe insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next
- 5. Multiple ChoiceA florist places a bouquet of white carnations in water containing blue dye. After a time, the flowers turn blue. What process helped the carnations to change color?Specific heatSurface tensionCohesion and adhesion of water moleculesFormation of covalent bonds between hydrogen and oxygen molecules
- 6. Multiple Choice
The makeup of most living things is water. It plays a vital role in maintaining internal conditions, like homeostasis. Which property of water makes it good at regulating temperature of most living organisms?
Water is a good solvent.
Water exhibits strong cohesion.
Water has an unusual crystalline structure.
Water has a high capacity for heat.
- 7. Multiple ChoiceWater has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead?Flooding would occur and animals would be forced to migrateHarmful organisms living in water would reproduce at a rapid rateOrganisms that are sensitive to changes in temperature would diePlants would not have enough water to effectively carry out photosynthesis
- 8. Multiple ChoiceMany fish and aquatic plants can survive a cold winter because the layer of ice that forms at the top of the lake insulates the water below and prevents the lake from freezing solid. What unique property of water contributes to this effect?Water absorbs heat when it evaporates and forms a gasWater expands and becomes less dense when it freezes.Water molecules completely separate into ions in solutions.Water forms hydrogen bonds with ions and other polar substances.
- 9. Multiple ChoiceWhich of the following characteristics of water is not a result of hydrogen bonding?adhesive strengthcapillaritycohesive strengthAll of the above are a result of hydrogen bonding.
- 10. Multiple Choicemolecule in which opposite ends have opposite electric chargescohesionpolar moleculehydrogen bondsolution
- 11. Multiple ChoiceWhy does water move from the roots to the leaves of plants?Water is pushed by solutesCapillary action pulls the water molecules like a chainWater is pulled by gravityWater’s cohesion causes it to “pull” towards the leaves
- 12. Multiple ChoiceAttractions between water molecules are calledCovalent bondsIonic bondsPolar bondsHydrogen bonds
- 13. Multiple ChoiceWater is polar because...The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.The molecule has two poles, at which the it is colder than other regions of the molecule.The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.The water molecule is neutral.
- 14. Multiple Choice
The curve in this meniscus is caused by the attraction between the water and the glass known as
solute
surface tension
cohesion
adhesion
- 15. Multiple Choice
A substance that increases the hydrogen ion (H+) concentration of a solution. On the pH scale: 6.9 or below is considered an
acid
base
neutral substance
concentrated substance
