What is a chemical change?
Carbon Dioxide and Water
What are the products of combustion?
Explains that states of matter are based on the amount of kinetic energy in the particles of a substance.

An ionized gas with so much energy that electrons are knocked off from atoms
What is Plasma?
A substance that flows/deforms under pressure
What is a fluid?
Gas = gaseous matter at room temperature, Vapor = gaseous state of a substance that is liquid/solid at room temperature
What is the difference between Gas and Vapor?
The amount of kinetic energy needs to increase to overcome inter-particle attraction
What has to happen to Inter-particle attractions in order for the state of matter to change?
The average kinetic energy of molecules in matter
What does temperature measure?
The lowest possible temperature where particles have no kinetic energy.
What is Absolute 0?
Only to the surface particles of a substance.
Where does evaporation occur?
Throughout ALL particles of a substance.
Where does boiling occur?
The less air pressure there is, the lower the boiling point
What is the relationship between boiling temperature and air pressure?
0, 273
What is the freezing/melting point in Celsius and Kelvin?
100, 373
What is the boiling/condensation point in Celsius and Kelvin?
The temperature where a liquid becomes a gas and its temperature no longer changes.
What is the boiling point?
Freezing point, boiling point
What are the two points that you need to make a Heating Curve?
Energy is being added to increase the kinetic energy of particles, which increases the temperature
What does an incline mean on a Heating Curve?
The transition between states of matter where the temperature is constant
What does a plateau mean on a Heating Curve?
The point where all three states of matter of a substance coexist
What is the triple point on a Phase Diagram?
Above this temperature is where a substance can no longer be a liquid
What is the critical point on a Phase Diagram?
different forms of the same element in the same state
What is an Allotrope?
It must have no volume, no interparticle attraction, and random movement
