- 1. Multiple Choice
Which liquid had the highest molecular mass?
Hexane
Petroleum Ether
Ethanol
H20
- 2. Multiple Choice
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.
- 3. Multiple Choice

A
B
C
Both D and E
- 4. Multiple Choice

Chlorophyll A
Chlorophyll B
Carotenoids
All the same
- 5. Multiple Choice
Which pigment had the lowest absorption rate at 500 nm wavelength?
Chlorophyll A
Chlorophyll B
Carotenoids
All the same
- 6. Multiple Choice
Which position produced the highest KE (kinetic energy)?
A
B
C
Both D and E
- 7. Multiple Choice
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.
