What type of energy is considered the energy of motion?
Kinetic Energy
A substance changing from a _________ to a __________ is caused because of melting.
Solid to a liquid
Snow forms in clouds because water vapor changes directly to ice. This is an example of _____.
Deposition
The surface particles of a sample of matter experience a strong downward pull and stretch tight enough for a spider to walk on it. This is an example of _____.
SURFACE TENSION
Draw what the particles look like in a solid
Example: Particles should be drawn close together
A change in the state of matter is caused if enough _____ is added to or removed from an object.
Thermal Energy
A substance turns from a liquid to a solid because heat is being removed. This process is called what?
FREEZING
During a hot shower, water vapor fogs up the cooler mirror when it turns to water. This is an example of _____.
Condensation

a. temperature
b. pressure
c. volume
d. heat
B. PRESSURE
Draw what the particles look like in a gas
Example: Particles should be spread out throughout the container
Adding thermal energy to a cup of water can cause the _____.

b. particles to get farther apart
c. particles to move faster or get farther apart or both
d. particles to remain constant
c. particles to move faster or get farther apart or both
Vaporization, including boiling and evaporation, are processes that cause a substance to change from a ________ to a __________.
Liquid to a gas

a. 40 degrees Celsius
b. 50 degrees Celsius
c. 55 degrees Celsius
d. 45 degrees Celsius
C. 55 degrees Celsius (the hotter the temperature, the faster the particles are moving)

Slowing down
Particles are always in _________________ motion.
CONSTANT
Draw what the particles look like in a liquid
Example: Particles should be spread out a little bit throughout the bottom of the container
Particle motion in ice is _____________ than particle motion in water.
SLOWER
Dry ice is a solid that changes directly to a gas when thermal energy is added. This is an example of _____.
Sublimation
When changing from a solid to a gas, are the particles speeding up or slowing down?
Speeding up
