Unit 3 States of Matter REview
Volume
The amount of space an object takes up.
The volume of this state of matter can change
gas
Deposition
gas to solid
In a testable question where would you always find the Independent and Dependent variable? How does ________ affect ________?
How does the independent affect the dependent?
In an appropriate hypothesis where would the independent and dependent variable be located? If we __________, then ___________, because.....
If we use this independent variable, then the dependent variable will...., because....
You would use a _________ graph if your data was measured over time
Line
Matter
Anything that has mass and takes up space.
You would use a _________ graph if your data was comparing
Bar
The variables in an experiment that are held constant among each test conducted
Control Variables
What does DRY MIX stand for?
Dependent Responding on the Y-axis and Manipulated Independent on the X-axis
The variable in an experiment that is measured (your data)
Dependent Variable
Difference between vaporization & boiling
Evaporating slowing turns liquid to gas, vaporization boils quickly to turn to gas.
Condensation
Gas to Liquid
The correct format for a hypothesis is...
If we..... then ... will increase/decrease, because....
The one variable in an experiment that is changed and tested.
Independent Variable
freezing
Liquid to Solid
How do you describe the particles in a liquid
Low intermolecular attraction between particles(still touching) but allows particle to slide past each other
How would you describe the particles in a gas
Particles moving very fast and freely. No intermolecular attraction.
When gasses are heated even further the next state of matter would be
Plasma
How do you describe the particles in a solid?
Strong attraction between particles. Locked tightly together (touching) and vibrate.
Mass
The amount of matter an object is made up of. Measured by a balance.
What does TAILS stand for?
Title Axis Intervals Label and Scale
Phase Change
When matter changes from one form to another
Absolute zero
When molecules completely stop because all heat is removed. Currently impossible.
Physical Properties
a characteristic that can be observed or measured without changing what the substance is.
Evaporation (absorbs or releases) heat
absorbs (gains)
Melting (absorbs or releases) heat
absorbs (gains)
Sublimation (absorbs or releases) heat
absorbs (gains)
On a data table the dependent variable goes...
across the top
On a data table the independent variable can be found...
along the side in the first column
Liquid to gas at the surface
evaporation
Evaporation causes the molecules to move...
faster & further apart
Vaporization causes the molecules to move...
faster & further apart
the state of matter with no definite volume and no definite shape
gas
term-38Another name for thermal energy
heat
the state of matter with a definite volume but no definite shape
liquid
Boiling
liquid changing to a gas under the surface
solid to liquid
melting
Condensation (absorbs or releases) heat
releases (loses)
Freezing (absorbs or releases) heat
releases (loses)
Condensation causes the molecules to move...
slower & closer together
Freezing causes the molecules to move...
slower & closer together
This state of matter holds its shape when placed in different size containers
solid
the state of matter with a definite volume and definite shape
solid
Sublimation
solid to gas
states of matter (common)
solid, liquid, and gas
