Solid, Liquid and Gas

All objects are made up of small particles.

​

Can you describe the particles in each state of matter?​

WILF: I can identify the effects of energy changes in the state of matter.

CHANGING STATES OF MATTER

Multiple Choice

All objects are made up of tiny _______ that are in motion.

• particles

• rocks

• minerals

Multiple Choice

Which state of matter has its particles tightly packed and vibrate in place?

• solid

• liquid

• gas

The average movement of particles in an object is determined by the amount of energy in the object.

​

Temperature is the measurement of this movement.​

WILF: I can identify the effects of energy changes in the state of matter.

CHANGING STATES OF MATTER

Multiple Choice

At higher temperatures, particles in an object move ________.

• slower

• faster

• the same

Add Energy: the particles will start to move quickly.

​

Remove Energy: the particles will slow down and move closer together.​

WILF: I can identify the effects of energy changes in the state of matter.

CHANGING STATES OF MATTER

Multiple Choice

What causes a change in the state of matter?

• removing energy

• adding energy

• both are correct

What happens when energy is INCREASED (or added)?

WILF: I can identify the effects of energy changes in the state of matter.

CHANGING STATES OF MATTER

1. Melting: Solid turns to Liquid​

2. Evaporating: Liquid turns to Gas

What happens when energy is DECREASED (or removed)?

WILF: I can identify the effects of energy changes in the state of matter.

CHANGING STATES OF MATTER

1. Condensing: Gas turns to liquid

2. Freezing: Liquid turns to Solid
