States of Matter
The three most familiar states of matter?
What are Solid, Liquid, and Gas
The reason that liquids "flow"
What is particles are close together but can slide past each other in order to "flow".
The phase change from gas directly to a solid.
Deposition
What is a solid?
This type of matter contains particles that are close together and vibrate in place.
A state of matter is determined by...
Particle arrangement, speed,
does it have a volume and shape?
What is a liquid?
Has definite volume and takes the shape of its container
This state of matter has particles moving fast enough to overcome nearly all of the attraction between them
no set volume or shape
The phase change from a solid directly to a gas.
Sublimation
Liquids take the shape of the container they are in..
This state has no definite shape or volume.
What is a gas?
The phase change from liquid to gas at the surface of the liquid.
evaporation - vaporization
This is H2O in solid form.
Ice
least = gases
middle = liquids
most = solids
What is the resistance to flowing...
What is viscosity?
This theory says all matter is in constant motion.
The Kinetic Theory of Matter
What two phase changes are endothermic?
melting and vaporization
What is plasma?
A state of matter with no definite shape or volume. It is a hot, energized gas where the atoms break apart into charged particles. These particles can carry electricity and respond to magnets. The fourth state of matter.
Temperature at which ice melts into liquid.
What is 0 degrees C and 32 degrees F?
Name two examples of plasma.
Lightening, the sun, stars, northern lights, flames
What two phase changes are exothermic?
condensation and freezing
What are the two types of solids?
Hint - one has a regular repeated pattern...
crystalline and amorphous
