a.a.MeltingMelting is a change of phase from solidsolid to liquid.
The temperate at which solid melt is its melting pointmelting point.
Melting point of waterwater is 0000 C C. Iron melts at 1525152500 C C.

b.b.FreezingFreezing is the change of phase from liquidliquid to solidsolid.
Freezing pointFreezing point is the temperature at which a liquidliquid changes to a solidsolid.
The freezing point of a substance is the samesame as its melting pointmelting point.

c.c.BoilingBoiling pointpoint the temperature at which a liquid boilsboils.
At its boiling point, a liquidliquid changes into a gasgas is called Vaporization.
d.Evaporation when a liquidliquid changes from a liquidliquid to a gasgas with out reaching its boilingboiling point.

e.Condensation
process where
waterwater vapor
changes to a liquidliquid.
f. Sublimation process where iceice changes directly to a gasgas with out changing to a liquidliquid first. Example comet

1.1.LatentLatent heatheat or or hiddenhidden heatheat is the energyenergy needed to change a substancesubstance from one physicalphysical state to another.
The temperaturetemperature does not change as long as the meltingmelting or freezingfreezing continues.
