STATES OF MATTER

The Five States of Matter

• Solid

• Liquid

• Gas

• Plasma

• Bose-Einstein Condensate

STATES OF MATTER

Depend on:

 Particle arrangement

 Energy of particles

 Distance between particles

STATES OF MATTER

SOLIDS

•Particles of solids are tightly packed.

•They are vibrating about a fixed position.

•Solids have:

• a definite shape

•a definite volume.

Heat

• Desks in rows

Analogy

STATES OF MATTER

LIQUID

 Particles of liquids are tightly packed…

 but are far enough apart to slide over one another.

 Liquids have:

 An indefinite shape

 a definite volume.

Heat

Analogy

• Students in crowed hallways

STATES OF MATTER

GAS

 Particles of gases are very far apart.

 They move freely and have a lot of energy.

 Gases have:

 an indefinite shape

 an indefinite volume. Heat

• Bees in a jar

Analogy

But what happens if you raise the temperature to super-high levels… between

1000 ° C and 1,000,000,000 ° C ?

Will everything just be a gas?

STATES OF MATTER

PLASMA

 A plasma is a gas with charged particles.

 A plasma is a very good conductor of electricity

 Plasmas, like gases have

 an indefinite shape a

 an indefinite volume.

Some places where plasmas are found…

1. Flames

2. Lightning

3. Aurora (Northern Lights)

The Sun is an example of a star in its plasma state

STATES OF MATTER

SOLID

Tightly packed, in a regular pattern

Vibrate, but do not move from place to place

LIQUID

Close together with no regular arrangement.

Vibrate, move about, and slide past each other

GAS

Well separated with no regular arrangement.

Vibrate and move freely at high speeds

PLASMA

Has no definite volume or shape and is composed of electrical charged particles

But now what happens if you lower the temperature way, way, down to

100 nano degrees above

“Absolute Zero” (-273°C)

Will everything just be a frozen solid?

Not Necessarily!

In 1924, two scientists, Albert Einstein and

Satyendra Bose predicted a 5 th state of matter which would occur at very very low temperatures.

Finally, in 1995, Wolfgang

Ketterle and his team of graduate students discovered the 5 th state of matter for the first time.

Ketterle and his students

The 5 th state of matter:

Bose-Einstein Condensate

In a Bose-Einstein condensate, atoms can no longer bounce around as individual particles .

Instead they must all act in exactly the same way, and you can’t tell them apart .

In 2002, Ketterle and two other scientists received the highest award in science for discovering Bose-Einstein condensate:

The Nobel Prize

The Kinetic Theory of Gases

1. All matter is composed of small particles .

2. They are in constant , random motion .

3. They constantly collide with each other and with the walls of their container.
