What happens to the amount of matter during a phase change?

a. stays the same

b. increases

c. decreases

The amount of matter stays the same! A

100

The reason that liquids "flow"

What is particles are close together but can slide past each other in order to "flow".

100
When liquids change to a gas.
What is vaporization?
100

The phase change from gas directly to a solid.

Deposition

100

What is a solid?

This type of matter contains particles that are close together and vibrate in place.

200

A state of matter is determined by...

Particle arrangement, speed, 

does it have a volume and shape?

200

What is a liquid?

Has definite volume and takes the shape of its container

200

Describe a gas...

This state of matter has particles moving fast enough to overcome nearly all of the attraction between them

no set volume or shape

200

The phase change from a solid directly to a gas.

Sublimation

200

Called a solid that has a very orderly, repeated pattern in arrangement of particles

Crystalline solid

300
These are the things that matter is made of?
What are atoms and molecules
300
Describe the shape of a liquid...

Liquids take the shape of the container they are in..

300

What is the name of water in a gas state of matter?

Water vapor

300

The phase change from liquid to gas at the surface of the liquid.

evaporation

300

Does freezing need energy or lose energy? Is that endothermic or exothermic?

freezing loses energy so exothermic 

400
Order the densities of the 3 states of matter from least to greatest...

least = gases

middle = liquids

most = solids

400
Does Vaporization lose energy or gain energy? Is that endothermic or exothermic?

Vaporization gains energy as a liquid turns to gas. This is endothermic

400

This theory says all matter is in constant motion.

The Kinetic Theory of Matter

400

What two phase changes are endothermic?

melting and vaporization

400
When matter changes from liquid to solid.
What is freezing?
500

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.

500

Temperature at which ice melts into liquid.

What is 0 degrees C and 32 degrees F?

500

Name two examples of plasma.

Lightening, the sun, stars, northern lights, flames 

500

What two phase changes are exothermic?

condensation and freezing

500

What is the name of the solid with no repeating pattern or consistent arrangement of particles?

amorphous solid
