4: Materials Flashcards
1
Q
State how increasing temperature affects the rate of a particle falling through a liquid.
A
As temperature increases, viscosity decreases, so rate of falling increases.
2
Q
State how increasing depth affects the rate of a particle falling through a liquid.
A
As depth increases, viscosity increases, so rate of falling decreases.
3
Q
Describe laminar flow.
A
No abrupt changes in direction or speed.
No mixing of layers.
4
Q
Describe turbulent flow.
A
Abrupt changes in direction or speed.
Mixing of layers.
Contains eddies.
