dont write on me

1. large bodies of water, such as lakes and oceans, do not quickly fluctuate (change) in temperature. what is the reason for this phenomenon?

a. water has a high specific heat capacity.
c. water acts as a buffer.
b. water is a versatile solvent.
d. water is an acid.

1. water is essential for life. its special properties make water the single most important molecule in plant life. which of the following properties of water enables it to move from the roots to the leaves of plants?

a. water expands as it freezes.
b. water is an excellent solvent.
c. water exhibits cohesive behavior.
d. water is able to moderate temperature.

1. maria, after finding no cold soda in the refrigerator, placed a can of soda in the freezer. she then proceeded to check her facebook and forgot about the soda. later that evening her brother went to get some ice and it was brown. marias soda can had split open. what is the best explanation for what happened?

a. as the water cooled, it adhered to the can, causing it to split.
b. when the water froze, it weakened the molecular bonds in the aluminum can.
c. when the water froze, the space between the water molecules expanded.
d. as the water cooled, the surface tension of the water decreased and the can collapsed.

1. florida, the “sunshine state” is a big supplier of citrus. although florida has a hot - humid climate, the state occasionally experiences light freezes during the growing season. to protect the fruit, citrus growers will spray the fruit with water for protection. which property of water helps to protect the fruit from the frost?

a. the adhesive property of water allows it to stick to the fruit.
b. the cohesive property of water creates a film that reflects cold.
c. water expands when it freezes, causing the ice particles to evaporate away from the fruit.
d. water resists temperature change and keeps the fruit at a constant temperature.

1. as you walk to school you notice droplets of water on the leaves of nearby plants. thinking back to science class you recall that this is caused by a property called cohesive behavior. which characteristic of the molecular structure of water allows for cohesive behavior between water molecules?

a. water molecules are polar
b. water molecules have a neutral ph
c. water molecules have a low viscosity
d. water molecules have a neutral charge

1. some fish are able to live in lakes with very cold water. which statement describes the characteristic of water that plays an important role in allowing fish to live in these cold - water lakes?

a. water is a versatile solvent, and the temperature is regulated by substances dissolved in the fresh water.
b. water forms hydrogen bonds with other water molecules at the surface of the water.
c. water freezes and decreases the temperature of the water in the lake.
d. water at the surface of the lake freezes and forms an insulation layer.

Explanation:

1. Water's high specific heat capacity means it can absorb or release a large amount of heat without a large temperature change, explaining why large - bodies of water don't quickly change temperature.
2. Cohesive behavior of water allows water molecules to stick together and move in a continuous column from roots to leaves in plants.
3. When water freezes, it expands because the space between water molecules increases, causing the soda can to split.
4. Water resists temperature change due to its high specific heat capacity, which helps keep the fruit at a more constant temperature and protects it from frost.
5. Water molecules are polar, which allows for hydrogen - bonding between them, resulting in cohesive behavior.
6. Water at the surface of the lake freezes and forms an insulation layer, which allows fish to live in cold - water lakes as the water below the ice remains liquid.

Answer:

1. A. Water has a high specific heat capacity.
2. C. Water exhibits cohesive behavior.
3. C. When the water froze, the space between the water molecules expanded.
4. D. Water resists temperature change and keeps the fruit at a constant temperature.
5. A. water molecules are polar
6. D. Water at the surface of the lake freezes and forms an insulation layer.
