5. Phase Change Diagram Temperature is a measure of kinetic energy!
point in which a liquid and its vapor (gas) can coexist.
the temperature and pressure at which all three phases of that substance coexist
Temperature is a measure of kinetic energy!
As temperature increases:
molecules move faster (more Kinetic Energy)
intermolecular forces become weaker

6. Phase Change Diagram Kinetic Energy- movement of the atoms
Temperature is a measure of kinetic energy!
Kinetic Energy- movement of the atoms
Potential Energy- stored energy
INCREASE temperature = INCREASE energy!
Intermolecular forces get weaker! KE PE
Evaporation
Gas PE KE
Condensation
Melting
Liquid
DECREASE temperature = DECREASE energy!
Intermolecular forces get stronger! KE
Freezing
Solid

______- matter that can not flow (definite shape) and has definite volume.
Example:

_______- definite volume but takes the shape of its container (flows).
Example:

10. 3 States of matter
____- a substance without definite volume or shape and can flow.
_______- a substance that is currently a gas, but normally is a liquid or solid at room temperature. (Which is correct: “water gas”, or “water vapor”?)
