.SOLIDS, LIQUIDS AND
GASES.BY: Alessia Bonilla, Veronique Villeda, Rafael Aguilar, Diego

SOLIDS Definite Shape No Definite Volume Particles: Very close together
TYPES OF SOLIDS: Crystalline Solids -Particles form a regular
repeating pattern, mostly made up of Crystals.
Amorphous Solids -Particles not arranged in a regular
pattern, plastic, rubbers, glass.
LIQUIDS Definite Volume No Definite Shape Particles are packed together, but more freely.
Fluid= “A Substance that flows.”
PROPERTIES OF A LIQUID Surface Tension: Result on an inward pull of molecules belonging to a liquid that brings the molecules on the surface more together.
Viscosity: The liquid’s resistance to flow.
GASES A gas is a fluid. No definite shape No definite volume Particles are spread apart
MELTING Melting is the change of a solid to liquid.
Occurs at a specific melting point called melting point. At its melting point the particles of a solid substance are vibrating so fast that they break free from their fixed positions.
FREEZING The state from a liquid to a solid is
called freezing. This process is the reverse of melting . At the freezing temperature the particles of a liquid are moving so slowly that they begin to form regular patterns.
VAPORIZATION Vaporization takes place when the
particles in a liquid gain enough energy to form a gas.
BOILING Another kind of vaporization is called
boiling occurs when a liquid changes to a gas below its surface as well as at the surface the results can be seen when the boiling liquid bubbles
CONDENSATION This is the opposite of vaporization this
occurs when particles in a gas loose enough thermal energy to form a liquid.
SUBLIMATION Occurs when the surface particles of a
solid gain enough energy that they form a gas. During sublimation particles of a solid do not pass through a liquid state as they form a gas.
FLUIDS
-Crystalline -Amorphous
-Surface Tension-Viscosity
-Evaporation-Boiling
Particles: fixedPacked: Closely together
-Move freely-Close
-Move freely-Far apart
SUBLIMATION
