Matter
anything that takes up space and has mass
Physical Properties
characteristics of matter that you can observe or measure directly
Reflectivity
the ability to reflect light
(physical property)
Matter

Physical Properties
characteristics of matter that you can observe or measure directly
Reflectivity
the ability to reflect light
(physical property)
Hardness
describes how easily something can be bent or dented (physical property)
Flexible
Flexible
describes how objects can bend without breaking (physical property)
Magnetic
describes objects that are attracted to magnets, usually made of metal (physical property)
Conductivity
the ability to transfer heat or electricity (physical property)
Conductors
materials that let heat or electricity travel through them easily
Insulators
materials that do not easily let heat or electricity travel through them
Solubility
the ability of one substance to dissolve into another (physical property)
Mixture
a combination of two or more different substances in which the substances keep their identities
Solution
a special kind of mixture that has the same composition throughout because its particles are mixed evenly

Physical change
the size, color, shape may change, but the matter itself is the same
Is changing the state of matter a physical change or chemical change?
*Physical change
What phase change?
solid + heat = liquid
*Melting
What phase change?
liquid + heat = gas
* Evaporation
What phase change?
liquid - heat = solid
*Freezing
What phase change?
gas - heat = liquid
*Condensation
Chemical Change
a change in which new matter is formed
Burning wood - physical change or chemical change?
*Chemical change
Cooking eggs - physical change or chemical change?
*Chemical Change
the smell produced by rotting trash - physical change or chemical change?
*Chemical Change
crumpling paper - physical change or chemical change?
*Physical Change
Boiling water/ evaporating- physical change or chemical change?
*Physical Change
Changing state of Matter Molecules are:
Packed tightly for Solid
Slightly separated for Liquid
spread out for Gas
Three States of Matter
solid, liquid, gas
solid
has definite shape and volume
particles are packed tightly
liquid
has no definite shape but definite volume
particles not as tightly packed and can flow past each other
Gas
has neither definite shape or no definite volume
particles have space between them to move freely
Boiling Point
212 ℉
Freezing Point
32℉
