Science ACT Practice

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

Which pigment had the highest absorption rate at 500 nm wavelength?

• Chlorophyll A

• Chlorophyll B

• Carotenoids

• All the same

Which pigment had the lowest absorption rate at 500 nm wavelength?

• Chlorophyll A

• Chlorophyll B

• Carotenoids

• All the same

Which position produced the highest KE (kinetic 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.

Which pigment had the highest absorption rate at 660 nm wavelength?

• Chlorophyll A

• Chlorophyll B

• Carotenoids

• All the same

Which pigment had the lowest absorption rate at 550 nm wavelength?

• Chlorophyll A

• Chlorophyll B

• Carotenoids

• All the same

Which of the following graphs best illustrates the relationship between the heat released by the foods listed in Table 1 and the change in water temperature?

• A
• B
• C
• D
