Vocab 1
This is the field that studies matter and how it changes.
What is chemistry?
french chemist responsible for the "Law of Conservation of Mass."
Who is Antoine Lavoisier
The distinct point at which a liquid changes to a solid.
What is freezing point?
Matter that is in a state where it is loosely packed and free to flow.
What is a liquid?
Matter that is in a state where it is widely spread apart and moving rapidly.
A chemical reaction in which energy is absorbed
What is an endothermic change?
Two or more elements that are together and chemically bonded.
What is a compound?
A chemical reaction in which energy is released.
The inward pull or force characteristic of liquid molecules.
What is surface tension?
The distinct point where a solid changes state into a liquid.
This type of mixture is easy to distinguish and separate.
The average of the total energy in a substance.
What is temperature?
The amount of space matter fills.
This type of mixture is not easy to distinguish and separate.
What is a homogenous mixture?
A liquids resistance to flowing.
What is viscosity?
This theory states that all of matter is made up of very tiny atoms.
What is the particle theory of matter?
A solid with an irregular pattern that melts at a range.
What is an amorphous solid?
A change in appearance only of matter.
Change in state from a liquid to a gas known to occur both within and at the surface of a liquid.
What is boiling?
DOUBLE JEOPARDY! DOUBLE POINTS!
The name of Blaise Pascal's father.
What is Etienne?
This is the change that requires an increase in thermal energy where particles move from closely packed to widely spread apart and moving rapidly.
What is sublimation?
A change in state accompanied by a loss in thermal energy where particles move closer together and are free to flow.
What is condensation?
A change in thermal energy in which particles at the surface of a liquid begin to break free and become widely spread apart.
What is density?
The tiniest particle that all matter is made up of.
What is the atom?
