Types of Phase Change
100

This state of matter has has no visible shape and fills its container.

What is a gas?
100

Transferring energy out of a substance makes the molecules move more ________.

What is slowly?
100
The molecules in a gas move __________ than the molecules in a liquid.
What is faster?
100
These two factors determine whether a phase change will occur.
What is molecular attraction and kinetic energy?
100
The phase change that occurs when a solid changes to a liquid.
What is melting?
200

This occurs when molecules that make up a substance experience a change to their freedom of movement and a the substance changes appearance.

What is a phase change?
200
Molecules can transfer energy to each other by _________.
What is collision?
200

The energy that an object has because it is moving.

What is kinetic energy
200
True or false: The molecular attraction of a substance can change.
What is false?
200

What is the phase change when a liquid turns into a gas?

What is evaporation
300

This phase of matter holds its shape and does not take the shape of its container.

What is a solid?
300
You can increase the kinetic energy of a substance by doing this to it.
What is heating it?
300

This is a measure of the average kinetic energy of the molecules of a substance.

What is temperature?
300
Isopropyl alcohol (rubbing alcohol) molecules have _________ molecular attraction than water molecules.
What is less attraction?
300

This is the type of phase change that occurs when a gas turns into a solid.

What is deposition?
400

This is the reason why a liquid can flow: because its molecules move _________ each other.

What is around?
400

When energy is transferred to or from a substance, it can change the molecules’ this.

What is freedom of movement
400
Heating a substance increases this form of energy in the molecules of the substance.
What is kinetic energy?
400

This occurs when the kinetic energy decreases enough so that the attraction between molecules pulls them together.

What is freezing?
400

This is the phase change when a solid turns into a gas.

What is sublimation?
500

A noticeably different form or state of the same substance. 

What is a phase?
500
This is a way to transfer energy out of substance.
What is cooling?
500
The more kinetic energy a substance, the greater the ______________________ the molecules have.
What is freedom of movement?
500
If substance A evaporates before substance B when the same amount of energy is transferred to it, substance A must have _____ molecular attraction?
What is less molecular attraction?
500

A substance with greater molecular attraction will _______ into a solid at a higher temperature than a substance with lower molecular attraction.

What is freeze
