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.

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.
