Boiling Point - --CORRECT ANSWER AS---The temperature at which a
liquid boils and turn into vapor

Chemical Properties - --CORRECT ANSWER AS---Characteristics of a
material that present during a chemical reaction or chemical change

Density - --CORRECT ANSWER AS---The amount of mass per volume

Diffusion - --CORRECT ANSWER AS---Mingling of substances and
movement from areas of high to low concentration

Extensive Properties - --CORRECT ANSWER AS---Properties that depend
on the state of matter

Intensive Properties - --CORRECT ANSWER AS---Properties that do not
depend on the state of matter

Melting Point - --CORRECT ANSWER AS---The temperature at which a
solid changes to a liquid

Non Polar - --CORRECT ANSWER AS---A type of covalent bond in which
2 atoms share electrons

Osmosis - --CORRECT ANSWER AS---Passage of fluid through a
membrane

,Physical Properties - --CORRECT ANSWER AS---Observable properties of
matter

Polar - --CORRECT ANSWER AS---A molecule that has negative and
positive effect

Specific Heat Capacity - --CORRECT ANSWER AS---The amount of
energy needed to change the temperature of 1kg of a substance by 1
degrees Celsius

Boiling - --CORRECT ANSWER AS---Liquid at a temperature at which it is
changing to a vapor
Requires addition of heat to change from liquid to gas

Condensation - --CORRECT ANSWER AS---Changing of a vapor to a gas
or liquid
Requires removal of heat

Critical Point - --CORRECT ANSWER AS---The temperature at which the
liquid and gas phases of a substance have the same density
Liquid and gas coexist

Freezing - --CORRECT ANSWER AS---Changing from a liquid to a solid
due to temperature
Requires removal of heat

Gas - --CORRECT ANSWER AS---A state of matter composed of
molecules in constant random motion

Liquid - --CORRECT ANSWER AS---A state of matter that has definite
volume but not definite shape

Melting - --CORRECT ANSWER AS---Changing from a solid to a liquid due
to temperature
Requires addition of heat, increasing vibrational and translational energy

Phase Diagram - --CORRECT ANSWER AS---A graph of physical states of
a substance under varying temperature and pressure

, Solid - --CORRECT ANSWER AS---A state of matter that retains its shape
and density when not contained

Sublimation - --CORRECT ANSWER AS---Changing from a gas to a solid
without becoming a liquid

Triple Point - --CORRECT ANSWER AS---The temperature and pressure
at which solid, liquid, and vapor phases of a pure substance coexist

Kinetic Molecular Theory - --CORRECT ANSWER AS---Molecular motion
changes as heat is added or removed. As the temperature of a substance
increases, the intermolecular forces that hold the molecules together are
broken, causing the molecules to move away from each other

Acid - --CORRECT ANSWER AS---A substance with a pH less than 7

alkaline - --CORRECT ANSWER AS---A substance with a pH above 7

Catalyst - --CORRECT ANSWER AS---A substance that increases the rate
of a reaction by lowering the activation energy required without undergoing
permanent chemical changes

Compound - --CORRECT ANSWER AS---A substances made 2 or more
elements

Element - --CORRECT ANSWER AS---Pure substances that cannot be
broken down into similar substances

Enzyme - --CORRECT ANSWER AS---Acts as a catalyst

Organic Molecule - --CORRECT ANSWER AS---A molecule found in a
living things that contains carbon

synthesis, decomposition, single replacement, double replacement,
combustion - --CORRECT ANSWER AS---List the 5 basic chemical
reactions.

Control Variable - --CORRECT ANSWER AS---Something kept constant
during an experiment
