Chapter 13: States of Matter
I. The Fluid States
A. Properties of Fluids
1) A fluid can be either a _________ or __________
2) Fluids exert _______________ by applying a force to a surface.
a) Pressure is the __________ on a surface divided by the _________________________________
b) The SI unit for pressure is the _______________ (Pa) which equals one Newton per square
meter (1 N/m2).
c) Standard atmospheric pressure is about 1.0 × 105 __________ or 100 __________.
B. Fluids At Rest
1) Pascal’s Principle states that any change in _______________ on a confined fluid is transmitted
undiminished through out the fluid.
2) This principle is applied to ____________________ systems where fluid is confined to two
connecting chambers.
C. Swimming Under Pressure
1) The pressure of water increases as you dive _______________ into the water.
2) The pressure of water on a body depends on the _______________ of the fluid, its _____________,
and the acceleration due to _______________.
3) The container’s shape has __________ effect on pressure.
D. Buoyancy
1) Archimedes’s principle states that an object immersed in a fluid has an upward force equal to the
_______________ of the fluid displaced by the object.
2) The difference between the _______________ force and the object’s _______________ determines
whether an object sinks or floats.
a) If the buoyant force is __________ than the weight of the object then the object will float.
b) If the buoyant force is __________ than the weight of the object then the object will sink.
E. Fluids in Motion
1) Bernoulli’s principle states that as the velocity of a fluid _______________, the pressure exerted by
the fluid _______________.
2) The flow of fluids around an object is represented by ____________________.

F. Forces Within Liquids
1) Cohesive forces are the _________________________ forces of attraction between the particles
within a liquid.
2) _______________ tension is the tendency of the surface of a liquid to contract to the smallest area
possible. (For any given volume, this shape is a _______________.)
3) _______________ is the attractive force that acts between particles of different substances.
4) Capillary action occurs inside a narrow tube when the adhesive force is __________ than the
cohesive force.
5) ____________________ is the process by which particles escape from a liquid.
6) ____________________ is the process by which gas particles return to the liquid state.
II. The Solid State
A. Solid Bodies
1) Elasticity is an object’s ability to return to its _______________ shape after the external forces are
removed.
2) If an object exceeds its elastic limit, then ____________________ occurs.
B. Thermal expansion is the property of matter, in both solid and fluid states, to expand when __________
and contract when __________.
1) Thermal expansion in solids
a) The change in length of a solid is ____________________ to the change in temperature.
b) Alpha () is the coefficient of _______________ expansion.
c) Beta (β) is the coefficient of _______________ expansion (β ≈ 3).
