Phases

Phase- and part of a system that has uniform composition and properties

COndensation- process by which a gas changes to a liquid

vaporization - process by which a liquid changes to a gas

Equilibrium- condition where two opposing changes happen at the same rate. liquid to gas and gas to liquid

Equilibrium vapor pressure- pressure exerted by the vapor in equilibrium with its liquid at a given temperature

Volatile liquids- liquids that evaporate readily, have weak attractive forces between particles

Boiling- conversion of liquid to vapor within the liquid as well as its surface

Boiling point- equilibrium vapor pressure equals atmospheric pressure

molar enthalpy of vaporization- amount of energy needed to vaporize one mole of a liquid at the liquids boiling point at constant pressure

freezing point- temp at which solid and liquid are in equilibrium at 1 atm

molar enthalpy of fusion- amount of energy as heat required to melt one mole of solid at the solids melting point

sublimation- solid to gas

deposition- gas to solid
