STATESOFMATTERChem4Kids - States of MatterDo Molecules Move?Yes, they sure do!How do they move?It depends on whether they are in a solid, liquid, or gas

Molecules in Solids:Molecules are packed tightly together

Have very little energy

Molecules in Liquids:Molecules are loosely packed

Have medium energy

Molecules in Gasses:Molecules are spread far apart

Have LOTS of energy

What is the main difference between solids, liquids, and gases?

10

Add or Subtract Energy. . .When energy is added, particles move fasterand spread apart!

When energy is taken away, particles move slower and get close together!

Gas (MOST energy)Solid (LEAST energy)Liquid (Medium energy)Video Questions:http://teacher.scholastic.com/activities/studyjams/matter_states/What makes molecules get close together or spread far apart?

What makes molecules move?

Phase ChangesWhen you change the amount of heat energy in a substance it will change from one phase to another.

STATES OF MATTERBased upon particle arrangementBased upon energy of particlesBased upon distance between particles

Kinetic Theory of MatterMatter is made up of particles which are in continual random motion.

STATES OF MATTERSOLIDS

Particles of solids are tightly packed, vibrating about a fixed position.

Solids have a definite shape and a definite volume. HeatSTATES OF MATTERLIQUIDParticles of liquids are tightly packed, but are far enough apart to slide over one another.

Liquids have an indefinite shape and a definite volume.

HeatSTATES OF MATTERGASParticles of gases are very far apart and move freely.

Gases have an indefinite shape and an indefinite volume.

But what happens if you raise the temperature to super-high levelsbetween 1000C and 1,000,000,000C ?Will everything just be a gas?STATES OF MATTERPLASMAA plasma is an ionized gas.A plasma is a very good conductor of electricity and is affected by magnetic fields.Plasmas, like gases have an indefinite shape and an indefinite volume.

Plasma is the common state of matterSTATES OF MATTER

SOLIDLIQUIDGASPLASMATightly packed, in a regular patternVibrate, but do not move from place to placeClose together with no regular arrangement.Vibrate, move about, and slide past each otherWell separated with no regular arrangement.Vibrate and move freely at high speedsHas no definite volume or shape and is composed of electrical charged particles

Some places where plasmas are found1. Flames

2. Lightning

3. Aurora (Northern Lights)

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