Viscosity - MCAT Physical

Card 0 of 7

Question

Which of the following would tend to decrease the viscosity of a liquid flowing through a pipe?

Answer

The factors that influence viscosity are:

1. The molecular structure of the given liquid (i.e. what liquid is flowing)

2. Temperature

3. Extreme pressure

Liquids become less viscous with increased temperature. As temperature increases, the molecules move faster relative to one another and spend less time in contact with each other. This behavior causes the intermolecular forces to decrease, so the viscosity decreases.

Compare your answer with the correct one above
