Mix and Flow of Matter Flashcards
Fluids can Flow, T or F
true
Define Viscosity
How quickly a fluid flows
Why is viscosity happening
The great amount of rubbing inparticles
Do fluids with a high viscosity Flow easily?
No
Do fluids with a low viscosity Flow easily?
Yes
What happens to the viscosity when the fluid becomes heated?
The fluid becomes less viscous(thinner)
WHat happens to the viscosity when the fluid cools?
The fluid becomes more viscous(thicker)
Does temperature affect viscosity
Yes
One way to measure viscosity is the _____ method
The ramp method
What is the ramp method
Pour different liquids down a ramp, the slowest one is the most viscous(thickest)
Why does Flow rate increase when the fluid is heated
The particles move more easily past each other
Why does Flow rate decrease when the fluid is cooled
The particles slow their movement and friction is increased
Definite Density
The amount of Matter in a given volume
Most common units for density
g/mL, g/cm3
What does the density depend on
- Whether the object is solid 2.Filled with ar pockets 3. something inbetween
