Flow= it keeps going without getting clogged eg:sand falling from ur hand
Strength=Being able to withstand a force eg: metals if you try punch the metal it wont break
Hardness=to see how easy it is to scratch the solid e.g: concrete is hard but you are able to scratch it
solubility=dissolving in an liquid e.g: salt dissolves in water
conduction of heat= transfer of energy to one atom to another with direct contact
Mixture of metals= brass, bronze, chrome (Alloys)
Malleable=able to be hammered without breaking (changing shape)
Matter=anything that takes space
states:

solid
liquid
gas
Most common states

solid=ice
liquid=water
gas=oxygen
Particles temperature= -273 Celcius
How does solids particles move?
They vibrate in fixed position
How do liquids particles move?
They move slowly around from position
How does a gases particles move?
They move everywhere colliding with eachother
What is hypothesis?
Prediciton made from observations
What is kinetic theory?
Theory that all matter is made out of particle
Liquids and gases can be poured/flow
Liquids and gases can be poured/flow
viscosity 
ability for liquids and gases to flow
compressed
Squashed with a force
Changing state 
Solid to liquid=melting
liquid to solid=freezing
liquid to gas=boiling
gas to liquid= condensation
gas to solid= deposition
solid to gas= sublimation
boiling point=100C
Melting point 0C
What is latent heat?
Extra energy being transferred
Evaporation 
getting enough energy from surrondings to become a gas
wind speed
Air particles have more kinetic energy which can be transferred to the evaporation parts
Four factors of evaportation
Temperature=Lots of Heat means more energy that can be transferred into liquid particles
surface area =evaporation occurs at the surface of a liquid from energy (also can be evaporated from surronding energy)
Heat causes liquids, solids, gases to expand
