Question:
Matter.
Answer:
Any physical substance that occupies space and has mass. Consists of molecules and atoms, and at
the atomic and molecular level that chemical transformations take place
Question:
Macroscopic Scale.
Answer:
Used to determine matter seen with the naked eye; where observations take place
Question:
Atomic Scale (or molecular scale).
Answer:
Is used when describing individual atoms or molecules; describe and explain chemical processes
here
Question:
Order of Magnitude.
Answer:
Determined by size, each class being a number of times (usually ten) greater or smaller than the one
before.
Question:
,Element.
Answer:
Simplest type of matter and is a pure substance that CANNOT be broken down or separated into
simpler substance. Characterized by the number and types of particles of which they are composed.
Question:
Atoms.
Answer:
Smallest indivisible unit of an element. Consist of 3 subatomic particles. Protons, Neutrons,
Electrons.
Question:
Chemical Compounds.
Answer:
Two or more elements are combined in a defined ration, but they can be broken down
Question:
Molecules.
Answer:
Collections of atoms that are held together by chemical bonds
Question:
Pure Substance.
Answer:
Contains only one type of element or compound and has a fixed chemical composition
Question:
,Physical Properties.
Answer:
Do NOT change chemical composition of the material when measured
Question:
Solid.
Answer:
At the macroscopic level, it is a dense material with a defined shape. At the atomic level, atoms or
molecules are closely packed together vibrating rapidly, but not moving past one another.
Question:
Liquid.
Answer:
Flows and takes shape of the container. Atoms and molecules are closely together and the vibrations
allow them to move past one another
Question:
Gas.
Answer:
No fixed shape or volume. Cannot be seen with the naked eye, but at the atomic level can be seen
with the naked eye. Space widely apart, rapidly moving apart, and do not act strongly with each
other
Question:
Melting Point.
Answer:
The temperature at which a solid converts into a liquid
, Question:
Freezing Point.
Answer:
Occurs at the same temperature as the melting point as energy is removed (temperature falls)
Question:
Boiling Point.
Answer:
The temperature at which a liquid converts into gas
Question:
Mixture.
Answer:
A substance made up of two or more elements or compounds that have not reacted chemically
Question:
Homogeneous Mixtures (Solutions).
Answer:
Mixtures that have a constant composition throughout the material
Question:
Heterogenous Mixtures.
Answer:
Mixtures in which composition is not uniform
Question:
