A
Atomic Mass Units- a unit of mass used to express atomic and molecular weights
B
Boiling Point- the temperature at which a liquid boils and turns to vapor
C
Catalyst- a substance that increases the rate of a chemical reactionwithout itself undergoing any permanent chemicalchange
D
Density- the ratio of the mass of a substance to the volume of the substance
E
Evaporate- turn from liquid into vapor
Enzyme- a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction
F
Friction- the resistance that one surface or object encounters when moving over another
G
Graphite- a gray, crystalline form of carbon that occursas a mineral in some rocks
I
Isotope- two or more forms of an element that have the same amount of protons, but have a varying amount neutrons
M
Melting Point- the temperature at which a given solid will melt
N
Neutrons- a subatomic particle with no charge
P
Protons- a subatomic particle with a positive charge
