Science Fact 2 - Changes of State

There are 3 types of states of matter: Solid, Liquid and Gas.
Things can change its state because of the temperature change.
The process of changing of state are in this picture below:
The processes melting, evaporation and sublimation gains heat or needs heat
The processes freezing, condensation and resublimation/deposition releases heat

1.Melting:
Process from solid to liquid.
example:
ice melting, chocolate melting, butter melting.
2.Freezing:
Process from liquid to solid
example:
ice in the freezer, making ice cream.
3.Evaporation:
Process from liquid to gas.
example:
drying clothes, opened methanol bottle.
4.Condensation:
Process from gas to liquid.
example:
steam of boiling water, water on the cold glass's surface, morning dew on the leaf.
5.Sublimation:
Process from solid directly to gas.
example:
camper in the wardrobe, dried ice.
6.Resublimation/Deposition:
Process from gas directly to solid.
example:
dried ice, snow.
