Structure of Matter
Define Definite Shape & Volume
The Shape of the material does not change and cannot be compressed.
Definite Volume will take the shape of whatever container it is in, but can't be compressed.
What state of matter conforms to its environment?
Liquid
Define Kinetic Energy
Energy in/of movement
What is the difference between a directly proportional reaction and a indirectly/inversely proportional reaction.
Directly Proportional means they increase or decrease together (both variables have are affected the same)
Indirectly Proportional means that the value of one quantity increases with respect to decrease in other.
What is pressure?
Pressure by gas molecules is a result of collisions against walls ( Pressure: Force/Area)
Define Indefinite Shape & Volume
Indefinite shape is where the sample will take on the shape of the container.
Indefinite Volume is where the sample will expand to fill the entire container.
Describe the atomic make-up of a Solid

What State of Matter in has the Highest AND Lowest Kinetic Energy?
Highest: Gas
Lowest: Solid
Whats the relationship between temperature and pressure?
Temperature ^ = Pressure ^
Temperature V = Pressure V

If melting happens with an increase of temperature, what happened to the KE of molecules during melting?
Increases
Whats the relationship between # of Molecules and pressure?
# of Molecules ^ = Pressure ^
# of Molecules V = PressureV
Directly proportional
