shows all threeequilibrium curves

vapor pressure

fusion

sublimation

TERM 17

evaporation

DEFINITION 17

when liquid becomes a vaporhigh speed molecules are

leaving a droplet of liquid until none is left.

TERM 18

DEFINITION 18

amount of heat required to completely convert a substance

to convert it to another phasethis occurs at constant temp

during this process

TERM 19

energy conservation

DEFINITION 19

heat lost to one part of the system must be gained by

another part

TERM 20

Zeroeth's law of thermodynamics

DEFINITION 20

if object A is in thermal equilibrium with object B

if object A is in thermal equilibrium with object C

thenobject B is in thermal equilibrium with object C

1st law of thermodynamics

conservation of energy statement the internal energy

statement the internal energy of a system is related to its

work and heat^U=Q-W

TERM 22

state of a system

DEFINITION 22

depends on its composition, temp, pressure, and volume

TERM 23

state function
