endothermic
release of heat
Exothermic
exothermic-organize
condensation
freezing
deposition
endothermic
Melting
Sublimation
Evaporization
Exothermic -Highest release of heat
Deposition
Δ heat lost or gained in the conversion involving solid and
liquid by 1 mole of substance
Molar Heat of Fusion (ΔHfusion)
s–l melting/fusion
heat is absorbed therefore +ΔHfusion
l—s (freezing/congealing)
heat is lost therefore -ΔHfusion
Δ required for the conversion involving liquid and gas by 1
mole of liquid substance.
Molar Heat of Vaporization (ΔHvaporization)
L → G (vaporization)
Heat is absorbed therefore (+) ΔHvap
G → L (condensation)
Heat is lost or release therefore (-) ΔHvap
Graphs that relate pressure and temperature to the state of matter.
A visual picture of the existence and extent of the presence of solid and
liquid phases in binary, ternary, and other mixtures.
