Which of the following statements best describes the changes observed in the graph?

• At T1, Sample 1 has a lower kinetic energy than does Sample 2.

• At T2, Sample 1 has a lower kinetic energy than does Sample 2.

• An increase in temperature leads to a decrease in kinetic energy.

• Water never undergoes a phase change.

Assume that water undergoes a phase change to a gas. Which of the following statements would be true?

• The attractive intermolecular forces of the escaping molecules are weak.

• The average kinetic energy of the water remains the same.

• The rate of movement of the gas molecules decreases.

• The gas will undergo no further phase changes.

Suppose a third sample of water is heated to a higher temperature than Sample 2. It is then found that a greater number of molecules escaped the liquid in Sample 3 than in Sample 2. Would these results be consistent with the

results depicted in Figure 1 ?

• Yes, an increase in temperature leads to a decrease in the number of escaping molecules in the liquid.

• Yes, as the temperature increases, it leads to more molecules escaping the liquid.

• No, the temperature reading of Sample 2 would be five times as high as that of the third sample.

• No, the average kinetic energy of the water will decrease.

It can be inferred from the passage that when a substance undergoes a phase change from a liquid to a gas it will:

• evaporate.

• condense.

• disintegrate.

• remain the same.

According to the passage, neonicotinoids are a type of:

• parasite

• pollinator

• pesticide

• pathogen

NGSS.HS-LS2-7

According to Scientist 1, neonicotinoids:

• have been directly linked to declines in honeybee populations.

• affect honeybees by increasing their vulnerability to parasites.

• provide agricultural benefits that outweigh the risk to honeybees.

• are the greatest threat to honeybee health in the United States.

Scientist 1 identifies all of the following crops as being highly dependent on pollination by honeybees except:

• cherries

• almonds

• carrots

• apples

NGSS.HS-LS2-6

The major difference between the two scientists' viewpoints is that:

• Scientist 1 believes honeybee populations should be saved, while Scientist 2 believes humans should not interfere with honeybee populations.

• Scientist 1 believes all threats to honeybee health should be addressed, while Scientist 2 believes that efforts should focus on the greatest threats to these populations.

• Scientist 1 believes honeybee populations are declining in the United States, while Scientist 2 believes that honeybee populations are stable.

• Scientist 1 believes neonicotinoids are harmful to honeybees, while Scientist 2 believes neonicotinoids do not pose any threat.
