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.
When a liquid crystallizes to a solid, the sign of entropy is negative. This is because the process involves a transition from a disordered state (liquid) to a more ordered state (solid), resulting in a decrease in the randomness or disorder of the system. Consequently, the entropy of the system decreases during this phase transition.
The formation of snowflakes in a cloud is primarily a physical change rather than a chemical change. As water vapor in the atmosphere cools, it undergoes condensation and crystallizes into ice crystals, which then grow into snowflakes. This process involves changes in state (from gas to solid) but does not alter the chemical composition of the water molecules.
Magma.
Lava or Magma is rock in its molten state.
Frozen juice bars are primarily in a solid state of matter. When juice is frozen, the water content crystallizes, resulting in a solid form that retains the flavor and other components of the juice. However, when they begin to thaw, they can transition to a liquid state as the ice melts.
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.
No, magma is already in a molten state. It is a mixture of molten rock, gases, and solids that exists beneath the Earth's surface. Magma can solidify to form igneous rocks when it cools and crystallizes.
Solids become liquids. A phase change.

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.
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.
When the force of magma pushing upwards equals the force of the rock pushing downwards, the system is said to be in a state of equilibrium. This balance prevents the magma from continuing to rise or the rock from collapsing further.
Magmatic limbo refers to a state in which magma is neither erupting nor solidifying but is instead trapped within the Earth's crust. This state can occur when the conditions for eruption are not met, leading to the accumulation of magma in magma chambers. This prolonged storage can affect volcanic activity and the evolution of the magma itself, potentially resulting in future eruptions or changes in the composition of the magma. Understanding magmatic limbo is crucial for assessing volcanic hazards and predicting future eruptions.
No, change of state is a physical change.
A change of state is a molecular change.
