Which liquid had the highest molecular mass?

a)

Hexane

b)

Petroleum Ether

c)

Ethanol

d)

H20

2.

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

a)

Yes, it is supported by Table 1.

b)

Yes, it is supported by Figure 1.

c)

No, because different molecular masses have differing viscosity levels.

d)

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

3.

a)

A

b)

B

c)

C

d)

Both D and E

4.

a)

Chlorophyll A

b)

Chlorophyll B

c)

Carotenoids

d)

All the same

5.

6.

Which position produced the highest KE (kinetic energy)?

a)

A

b)

B

c)

C

d)

Both D and E

7.

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

a)

Yes, and it is Ethanol

b)

Yes and it is H20.

c)

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

d)

No, because all liquids have the same density.
