As the temperature of a polymer melt increases, the melt viscosity will:
Understand the Problem
The question is a multiple-choice question about the relationship between the temperature of a polymer melt and its viscosity. Specifically, it asks how the melt viscosity changes as the temperature increases.
Answer
The melt viscosity will decrease as the temperature of a polymer melt increases.
The correct answer is B) Decrease
Answer for screen readers
The correct answer is B) Decrease
More Information
As temperature increases, the viscosity of a polymer melt decreases because the molecules have more energy and can move more freely.
Tips
A common mistake is to think viscosity increases with temperature, but this is generally not true for polymer melts.
