It is according to what kind of material the lava is made from. If there are different minerals in the lava, then it is according to what temperature the mineral returns to the solid state, or a rock. Some minerals have a liquid temperature, close to the liquid temperature of another minerals, and chances are they will form in the same rock. Temperature determines what the rocks will become. Like gold is found in quartz. Their liquid temperatures are close so they form together.
Liquid to solid.
I do not no
Lava or Magma is rock in its molten state.
Magma is the molten material beneath the surface (crust) of the earth. Magma is called lava when it emerges from the earth in its molten state. The volcano is the geologic structure at the end of a volcanic chimney, which is the duct that connects the magma pocket in the earth through the crust to the surface. The volcano is actually at the "output end" of that volcanic tube.
Magma is constrained within the volcano. It may be exposed as a 'lava lake' but it in its molten state is magma. Lava is an exudate from a volcano. My geological dictionary does not strongly constrain the terms.
The mantle , made up of molten rock called magma.
Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. A rock with larger mineral crystals is said to have a coarse texture.
Your question as phrased is unclear. I will proceed to answer both interpretations I have of your question. Note: When magma crystallizes, it forms igneous rocks. 1) What is the change of state when magma forms from igneous rock? - Melting. Rocks are the solid state of matter and magma is the liquid state (although it can be a very viscous liquid). Changing something from solid to liquid is melting. 2) What is the change of state when magma crystallizes to form igneous rocks? - Solidification/Freezing. Magma becomes too cold to continue in a liquid state, it solidifies and crystallizes into solid igneous rocks: freezing.
Solids become liquids. A phase change.
The liquid state of stone.
It's very high temperature down in mantle so it resulting a solid rock to change into "molten" state. The molten material in the mantle is magma.

There is no solvent in magma. Rocks turn to a liquid state because of super-heating, not because the solids were dissolved in any solvent.

No, change of state is a physical change.
A change of state is a molecular change.
