Question

With the increasing molecular mass of a liquid, the viscosity.

• A. decreases
• B. increases
• C. no effect
• D. all are wrong

Answer 1

The correct option is B increases

With the increasing molecular mass of a liquid, the viscosity increases.

For large organic molecules formed by combining a number of smaller molecules such as plastics, viscosity is generally higher for polymers with higher molecular weights, where bigger molecules lead to higher viscosity..
