Section 2: States of Matter (Solid, Liquid, & Gas)
Deposition
gas to solid, without directly becoming a liquid
Temperature, what does it measure?
Temperature measures the average kinetic energy of molecules and atoms.
What is plasma?
Possible fourth state of matter high-energy state of atoms and molecules
What are the three states of matter?
Solids, Liquids, & gases
What is happening when to particles of a material when heat energy is transferred to the material and the temperature increases?
Temperature increases: molecules begin to move faster
Kinetic Molecular Theory
all molecules = constant motion & is different for the three states of matter
Normal Freezing Point
changes material from liquid to solid, at 1 atm
Normal Boiling Point
changes material from liquid to state, at 1 atm
Normal Melting Point
changes material from solid to liquid, at 1 atm
Vaporization
liquid to gas
Solid
molecules that have definite shape and volume & cannot be compressed
Liquid
molecules that have definite volume but not definite shape, and cannot be compressed
Gas
molecules that have indefinite shape and volume & can be compressed
Thermometers
number corresponding temperature
Sublimation
solid to gaseous state
