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. (They skip a phase)
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
In a liquid, molecules move in this manner
What is slide past one another
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
Water boils at 100C, it will/will not increase in temperature.
What is will not?
200
This is another name for stored energy.
What is potential energy?
200
The particles in this phase have random motion and no definite shape.
What is a gas.
300
water molecules have the most motion in this form.
What is steam?
300
Two containers are filled with H2O but the particles in one container are vibrating and different speeds and the molecules are spaced farther apart How can this be?
What is the containers are holding different phases of H2O?
300
When water boils, water molecules will move...
What is farther apart?
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
Molecules are gaining the most energy when they are freezing.
True?false
If false when is the most energy gained
What is false, evaporating?
400
Increasing temperature of any matter increases this
What is the motion of particles?
400
A melting candle represents what phase change.
What is solid to liquid?
400
Can gases have a definite shape?
What is no?
400
Temperature is a measure of this type of energy in particles.
What is kinetic energy?
400
Increasing the temperature will cause this.
what is increased movement of particles?
500
Water molecules are closes and have the least amount of motion in this phase
What is frozen or ice?
500
Particles in a gas have the greatest motion. (True or False)
What is True?
500
Gases have a definite volume
True/False
What is false?
500
states that matter is composed of a large number of small particles—individual atoms or molecules—that are in constant motion.
What is Kinetic Theory of Matter?
500
In this change of state of matter, the particles start out being able to move over each other, have no fixed shape and have a fixed volume. When they change state, they vibrate in place, have a fixed shape and a fixed volume.
