ACT Aspire Practice Test #2

Which liquid had the highest molecular mass?

• Hexane

• Petroleum Ether

• Ethanol

• H20

A scientist has that the larger the molecular mass, the larger the viscosity. Is he correct?

• Yes, it is supported by Table 1.

• Yes, it is supported by Figure 1.

• No, because different molecular masses have differing viscosity levels.

• No, because viscosity is the same for all molecular masses.

Which position produced the highest PE (potential energy)?

• A

• B

• C

• Both D and E

Does the liquid with the highest density also have highest viscosity?

• Yes, and it is Ethanol

• Yes and it is H20.

• No, because H20 has second highest viscosity while it has the highest density.

• No, because all liquids have the same density.

Cattle have mainly fed on grass in a particular region in Texas for the past 40 years. Recently, the population of cattle has doubled. What effects might this growth have on the ecosystem?

• The cattle are diseased.

• Next year, the cattle population will have tripled.

• The cattle need more space or more grass.

• The cattle need less space or less food.

Fishermen have recently begun fishing near Antartica. Due to their success, they plan to expand their business and capture thirty to fiftty times as many fish. What effects might this have on the ecosystem?

• The fish might become endangered.

• Any prey of these fish might overpopulate.

• Both answers are correct.
