Energy due to motion

Kinetic Energy

1000

This type of matter has particles that are packed tightly together

solid

1000

What is melting?

Solid turns into a liquid. 

1000

What happens to thermal energy when the particles move faster?

Thermal energy increases. 

1000

What is a solid?

State of matter with a definite shape and a definite volume

2000

What is potential energy?

Stored energy

2000

Describe the particle motion in gases

quickly & freely

2000

Water turning into ice is an example of this

freezing

2000

Which state change causes dew to form?

Condensation

2000

On a state change triangle, the arrow starts at a liquid and points to a solid.  What state change occurred?

Freezing

3000

The measure of the average kinetic energy of the particles of an object

temperature

3000

This state has particles that can slide past each other

liquid

3000

Vaporization occurs when what happens?

Liquid turns into a gas. 

3000

What do you have to do in order for a gas to turn into a liquid?

Remove thermal energy

3000

The total kinetic and potential energy of the particles is called what? 

Thermal energy

4000

The uneven forces acting on the particles in a liquid

surface tension

4000

Describe the attraction level between the particles in a gas

little to none

4000

Dry ice is an example of this state change

sublimation
4000

What three state changes occur when you REMOVE thermal energy?

Freezing, Condensation, Deposition

4000

On a state change triangle, the arrow starts at a gas and points to a solid.  What state change occurred?

Deposition

50000

The measure of a liquid's resistance to flow

viscosity

50000

Describe the particle arrangement, the movement of particles, and the attraction level between the particles in a SOLID.

Particles are packed tightly together, particles vibrate back and forth, attraction level between particles is very strong. 

50000

Describe the TWO types of vaporization. 

Boiling- occurs within a liquid & Evaporation- occurs at the surface of a liquid

50000

What three state changes occur when you ADD thermal energy?

Melting, Vaporization, Sublimation
