In the phase change, particles go from a solid to a liquid.
What is melting?
100
In the phase change, particle go from a solid to a gas.
What is sublimation?
100
In this phase liquids change to a gas.
What is evaporation/boiling or vaporization?
100
This type of energy is caused by movement.
What is kinetic energy?
100
This law states that mass is conserved during a phase change.
What is the law of conservation of mass?
200
In this phase change, heat energy is taken away.
What is freezing?
200
The frost on the ground after a cold night reprsents this phase change has occurred.
What is deposition?
200
In this phase change, latent heat energy is released.
What is condensation?
200
This is another name for stored energy.
What is potential energy?
200
The amount of water after heating 22 grams of water to the boiling point, and after several minutes all of the water is evaporated into a balloon.
What is 22 grams?
300
In this phase changes, heat is absorbed by water molecule, causing them to move faster and more freely.
What is melting?
300
In this phase change, the particle movement increases.
What is sublimation?
300
Evaporation is a process where energy is absorbed by the molecules. (True or False)
What is True?
300
An example of this type of energy at its greatest is a roller coaster at the top of a hill.
What is potential energy?
300
The amount of iron that is in the left in the foundary after 450 grams have been melted.
what is 450 grams?
400
During this phase change, water becomes a solid at 273 Kelvin
What is freezing?
400
Two balloons are filled with air. One of the balloons is placed into the freezer for 20 minutes. Explain why the balloon in the freezer shows a decrease in VOLUME.
What is "freezing the balloon decreases the kinetic energy of the particles inside of it. The decreased kinetic energy increases the attraction between the particles.
400
This process cools the surface that it is leaving because the molecules require additional heat energy to complete the phase change.
What is evaporation or vaporization?
400
Temperature is a measure of this type of energy in particles.
What is kinetic energy?
400
Differences in the temperatures of a substance also create differences in __________ which result in ____________ of matter.
density; movement
500
This is a critical temperature for water at which two phase changes occur at the same time. Identify the temperautre and the phase changes.
What is zero degrees Celsius? What are freezing and melting?
500
Two examples of deposition (correct answer will be either accepted or rejected by your teacher).
What are __________________ and __________________?
500
In this phase change, the motion of the particles decreases and energy leaves or exits the molecules.
What is condensation?
500
This must be absorbed or released to change from one state of matter to another state of matter.
What is heat energy?
500
In freezing, 235 grams of particles start out being able to move over each other, have no fixed shape and have a fixed volume. When they change state, this amount of particles vibrate in place, have a fixed shape and a fixed volume.
