Transcript Phases of Matter

Phases of Matter


Matter is anything that has mass and takes up space
Matter is the material that makes up all the things in the
universe


Except for forms of energy like heat, light, and sound
Energy is not something made of matter; it is the ability to get work done

All matter is made up of tiny particles called atoms
 There are 3 states or phases in which matter exists:
 Solids
 Liquids
 Gases
 Water takes one of the 3 phases throughout the water cycle:



Solid - ice, snow, hail, sleet
Liquid - rain, run-off, ground water, ponds, reservoirs
Gas - water vapor in the air from evaporation and transpiration, steam
Solids
 Most
objects around you are solids
 A solid is a phase of matter that has a
definite shape and a definite volume
 Volume is the amount of space an object
takes up
 Solid particles are tightly packed together
 Particles cannot change position easily
 Particles can only vibrate back and forth
 Examples: ice cubes, desks, chairs, pens
Liquids
 A liquid
is a phase of matter that has a
definite volume, but no definite shape
 Liquids can change shape because their
particles glide past one another (like iceskaters)
 A liquid will take the shape of its container
 The volume will remain the same
 Examples: water you pour into a glass, milk,
fruit punch, melted chocolate
Gases
 A gas
is a phase of matter that has no definite
shape and no definite volume
 Gases take the shape of whatever they are
put into
 Think of air inside a balloon, a bicycle tire, or
in a football
 Particles move freely to all parts of a container
therefore having no definite shape or volume
 Examples: air, oxygen, carbon dioxide, helium,
nitrogen, water vapor (steam)
Arrangement of Molecules for
each state of matter:
Solid
Liquid
Gas
