This is the definition that particles can move in any direction and can have different speeds.
What is random motion?
100
This is a state of matter with a fixed volume, but not a fixed shape.
What is a liquid?
100
This is the average kinetic energy of the particles in a material.
What is temperature?
100
This is vaporization.
What is the change from a liquid to a gas?
100
This is sublimation.
What is the change of a solid to a gas without going through the liquid state?
200
This is matter with a fixed shape and a fixed volume.
What is a solid?
200
This is a state of matter that has no fixed shape or volume.
What is a gas?
200
This includes both kinetic energy and potential energy of the particles in a substance.
What is thermal energy?
200
Vaporization the occurs at the surface of a liquid is called this.
What is evaporation?
200
This is deposition.
What is the change of a gas to a solid without going through the liquid state?
300
This is why the attractive force in particles in a solid are so strong.
What is because the particles are so close together?
300
In this state of matter, particles are close together, yet are able to move past each other.
What is liquid?
300
Adding thermal energy to a material and removing thermal energy to a material with do these.
What is heat it up when you add thermal energy, cool down the material when you remove thermal energy?
300
This is the change from a gas to a liquid.
What is condensation?
300
This is an example of deposition.
What is frost forming on a leaf?
400
Particles in any form of matter are always doing this.
What is moving?
400
This is how you would describe the particles in a gas.
What is the particles have a weak attractive force between other particles, they are very far apart, they are free to move, and they have a lot of energy?
400
This is a material changing from a solid to a liquid.
What is the melting point?
400
Describe the process of vaporization.
What is thermal energy must be added to the material?
400
This is an example of sublimation.
What is dry ice changing to a gas?
500
Describe how particles in a solid are moving?
What is they are moving very slowly in random directions. They have little energy.
500
This can cause the direction and speed of a particle in a gas to change?
What is collisions with other particles and with sides of the container?
500
This stays the same during melting, boiling, and freezing.
What is the temperature?
500
This is how you could increase the rate at which condensation occurs on a glass of water.
What is remove thermal energy?
500
This is the coolest teacher at Integrity Charter School.
