4A state of matter is the physical form in which substances exist.Solid Liquid GasPlasma

HOW MANY STATES OF MATTER?

STATES OF MATTER

Matter consist of atoms and moleculesNow the way that these particles move determines which state of matter that substance is in.

SOLIDS

In solids particles do not move fast enough to overcome the strong attraction between themThey are held tightly in placeThe particles just vibrate in place

CrystallineHave an orderly 3-d arrangement of particlesThat means that they are arranged in repeating pattern rowsIron, diamond, and ice

AmorphousParticles are in no

particular orderEach particle is in a

spot, but no organized pattern

Rubber, and waxNo true melting

point

2 TYPES OF SOLIDS

The particles in a liquid slide pass one another until the liquid conforms to the shape of its containerSince the particles are so close together its hard to push them closer together Ex. Hydraulic systems

LIQUIDS

LIQUIDS

LiquidsDefinite volumeBut no definite shape

• Name the 4 states of matter

• How do the particles in solids move?

• Example of crystalline and amorphous solids• How do the particles in liquids move?

REVIEW

Surface tension- tension on the surface of water that acts like a thin layer of skin.

LIQUIDS

LIQUIDS

Viscosity- Liquids resistance to flow

Gas is the state where matter changes in both shape and volumeThe particles in gas move fast enough to break away from each otherIn gas there is empty space between particles

Pressure- is the amount of force exerted on a given area

With gas the greater the particles and the faster they collide, the higher the pressure is

GASES

Boyle’s Law

At a constant temp. the volume increases as the pressure decreasesAt a constant temp. volume decrease as the pressure increases

GASES

GASES

Charles’s Law

At a constant pressure, with and increase in temp the volume also increasesAt a constant pressure, with an decrease in temp the volume will also decrease

PLASMAS

99% of the known matter in the universe is made of the state called plasmaPlasma is the state of matter that does not have a definite shape or volume

PLASMAS

Plasmas conduct electric currentNaturally are found in lightening, fire, and the incredible light show called aurora borealisArtificial plasmas fluorescent lights and plasma balls

Explain the difference in solid, liquid,gas, and plasma.What is the difference with Boyle’s law and Charles’s lawIn which state do the particles just vibrate
