When you turn a solid into a liquid you melt or liquefythe solid. Usually, this process requires heat to make the substance's molecules force each other far enough away that they can no longer maintain their form, and become a liquid.
the change of a liquid to a solid is freezing point and the change of a solid to a liquid is a melting point
Freezing... If you have any other questions just think of water. It freezes to ice, or a solid. Condenses to gas. And ice would melt to water.
The change in state would be known as melting.
Just for your information:
Solid to Liquid = Melting
Liquid to Gaseous = Boiling
Gaseous to Liquid = Condensation
Liquid to Solid = Freezing
melting
Some substances can go straight from solid to gas phase by a process called sublimation. A gas going to a solid is a process known as Deposition.
Solid, because it goes through a longer process than the Liquid. Thus, the Liquid doesn't need as much energy as a solid.
freezing melting
Dry ice, or solid CO2, In a physical change called sublimation. Other solids go through this phase too, however.

Both! The physical state of a substance can go straight from gas to solid, or can heat from solid to liquid and then to gas. The process a solid undertakes when it goes straight to its gas state from a solid state without first turning liquid is called sublimation.
Solid, because it goes through a longer process than the Liquid. Thus, the Liquid doesn't need as much energy as a solid.
freezing melting
The solid starts to warm up and when its temperature reaches its melting point, it will melt into a liquid or in some cases it will go directly to gas form (this process is called sublimation.)
The latent heat of fusion
gas to liquid = condensation liquid to solid = freezing the gas must go through a liquid state, Even if for a millisecond.
Yes. Gas can go directly to a solid by a process called deposition, also known as desublimation. An example is sub-freezing air, where water vapor turns into ice without first becoming liquid.
sublimation
Yes, this process is called sublimation.
Dry ice, or solid CO2, In a physical change called sublimation. Other solids go through this phase too, however.
