Ch. 2 Changes

Review of physical and chemical changes

change resulting in a new composition chemical change
phase change from gas to liquid condensation
defined area withing a mixture phase
phase change from solid to gas sublimation
change where the composition remains the same physical change
phase change from solid to gas sublimation
amount of matter object has mass
property based on the type of substance intensive
gas state of substance that is normally a solid or liquid at room temperature vapor
state of matter: indefinite shape and definite volume liquid
a physical blend of 2 or more substances not in a fixed ratio mixture
property based on the amount of substance extensive
state of matter: particles do NOT move freely solid
physical separation based on size filtration
phase change from liquid to gas boiling/evaporation
mixture that looks different heterogeneous
is made of 1 type of atom; can't be chemically separated Ex. Neon element
property that can be observed without changing the composition physical property
property that can only be observed by changing the composition chemical property
amount of space taken up by object volume
the chemical blending of 2 different elements in a fixed ratio compound
phase change from liquid to solid freezing
phase change from solid to liquid melting
aka homogeneous mixture solution
most common state of matter on earth (UPPER CASE) LIQUID
most common state of matter in universe (UPPER CASE) PLASMA
mixture that looks the same homogenous
