1. Define the
word “fluid” (4.1 page beginning on pate 110)
2. Use the particle theory to explain why liquids and gases are fluids, but
solids are not. (4.1)
3. Give some characteristics of liquids and solids that are the same.
What are some characteristics that are different? (4.1)
4. Explain how
liquids and gases are similar. How
are they different? (4.1)
5. Describe how to measure viscosity. (4.2)
6. Explain flow to determine the flow
rate of a liquid. (4.2)
7. Summarize the main factors that
affect the viscosity of liquids and gases.
8. Use the key terms above to fill in
the blank:
a) _______________ chocolate causes it
to flow. (4.1)
b) A _____________ always has an even
surface. (4.1)
c) A _____________ can be poured only if
it is ground into a fine powder. (4.1)
d) _____________ occurs when dishes “air
dry” on a rack. This change of state is called __________________. (4.1)
e) The particles of a ________________
are spread extremely far apart. (4.1)
f) Liquid water can change into a gas at
its _______________ 100 degrees Celsius.
g) A fluid’s resistance to flow is known
as its ___________________; a good way to measure this property is by
determining the ______________ of a liquid. (4.2. 4.3)
h) There is ____________________ between
the particles of a fluid that causes viscosity. (4.3)
