States of Matter
|
Solid
Liquid Gas |
|
|
Boiling Point
|
Temp. @ which a substance changes from a liquid to a gas;a physical property
|
|
|
Chemical Property
|
property that can only be observed when there is change in the composition of the substance.Ex.Abiltity 2 Burn
|
|
|
Chemical Change
|
A change in which one or more substances combine or break apart to form new substances Ex.Rusting,burning,food spoiliong, change in color or odor
|
|
|
Physical Property
|
characteristic of matter that can be measured and observed w/o changing the makeup of the substance Ex.size,color,texture,state, odor,mass,density
|
|
|
Physical Change
|
change in which the appearance or state of matter changes but the substance's properties and makeup remain the same.Ex.Dissovling,melting, evaporating,tearing,folding
|
|
|
Evaporization(vaporization)
|
When a liquid changes to a gas
|
|
|
Condensation
|
When a gas changes into a liquid(opposite of vaporization)
|
|
|
Sublimation
|
When a solid changes directly into a gas
|
|
|
Deposition
|
When a gas changes into a solid(opposite of sublimation)
|
|
|
Calculating Density
|
mass / volume= Density (remeber HEART;top is the M,bottom is the V,and put a line through the middle)
|
|
|
Mass
|
D X V(Density and volume combine to create mass) (Law of Conservation of Mass states that mass cannot not be created nor destroyed. A candle lost mass when it was burned,but the mass lost was combined with the gases in the air to form new substances.So mass was not created or destroyed.)
