What does agitation do?

5

Fill in the Blanks for Viscosity(notes will help):

Viscosity is the property that describes a fluid's or . Thicker liquids are viscous or have a higher . is used to determine viscosity. This is a measure of the it takes a liquid to travel a certain . Viscosity relates to the of . Viscosity is thought of as to .
- There is between
- liquids have more attraction between the , and therefore, more
- a substance causes the particles to spread , creating internal friction

For , the opposite is true. As they are , they become more .

1

Fill in the Blanks(notes do not apply, but I have said this many times):

The more a substance is, the would be less.

1

What is density?

1

What units do you use to measure capacity?

1

What units do you use to measure volume?

1

2

are generally the most dense. Next is and then .

2

100g of nickel occupies 11.2 cc. What is the density of nickel?

3

is the tendancy for materials to rise or float in a . It is also referred to as " ", which is the force on objects submerged in fluids. occurs when an object doesn't fall or sink in a fluid, but remains .

1

Check FOUR things that cause floating:

1

Fill in the Blanks for Archimedes Principle:

The Force acting on an object the (force of gravity) of the displaced by the .

1

If the Bouyant Force is the same as the gravitational force, the object will neither sink nor float.

1
