States of MatterStates of Matter: The physical forms in whicha substance can exist.Matter consists of tiny particles called atomsand molecules.– They cannot be seen with out a powerful microscope– They are always in motion and are constantly bumping into each other.
SolidsSolid: the state in which matter has a definiteshape and volume.There are two types of solids- Crystalline-have a very orderly, three-dimensional arrangement of atoms or molecules. (Iron, Diamond and Ice)- Amorphous-are composed of atoms or molecular that are in no particular order. (Rubber and Wax)
LiquidLiquid: the state in which matter takesthe shape of its container and has adefinite volume.Liquids can change shape, but notvolume.
Important properties of liquid!Surface Tension: the force acting on theparticles surface of a liquid that causesthe liquid to form spherical drops.Viscosity: the liquid’s resistance to flow.(Honey has a high viscosity whencompared to water).
GAS!!Gas: the state in which matter changesin both shape and volume.The atoms of gas move fast enough tobreak away from each other.
PressurePressure: The amount of force exertedon a given area.
Laws that describe the behavior of Gas!Boyle’s Law: states the for a fixedamount of gas at a constanttemperature, the volume of a gasincreases as its pressure decreases.Weather balloons are a good example!
More LawsCharles’s Law: states that for a fixed amountof gas at a constant pressure, the volume ofthe gas increases as its temperatureincreases.Example: Put a balloon into the freezer andwait for 10 minutes.
PlasmaPlasma: the state of matter that doesnot have a definite shape or volumeand whose particles have broken apart.Plasmas conduct electric current.Electric and magnetic fields effectplasmas.
Plasmas ContinuedNatural Plasmas are found in lightning,fire, and the aurora borealis.Artificial Plasmas are found influorescent lights and plasma balls,created by passing electric chargesthrough gases.
Anything you write down fromthe next slide, you can use onthe test! You’d better be quick about it! Ready, get set, GO!
