Freezing.
There are several names for when a solid changes to a liquid. Usually, melting of a solid occurs when heat is used near the solid and it changes it to a liquid.
What type of change occurs when water changes from a solid to a liquid
condensation
Freezing occurs.
You are adding heat/energy. It is melting.
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.
If we take solid, liquid and gas being the three main states of matter (plasma being an arguable fourth), then from solid to liquid, the process melting occurs, from liquid to gas evaporation or boiling (they are different things) occur. Then from gas to liquid condensation occurs and from liquid to solid freezing occurs.
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
The change is phase from solid to liquid and form liquid to gas (as well as changes in the reverse direction).
The process of a solid changing into a liquid is called melting. This occurs when the temperature of the solid reaches its melting point, causing the solid to transition into a liquid state.
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
