Is lava cooling into lava rocks a chemical change?
No. This is simply a change of state from liquid to solid. It is a physical change.
What happens when a substance reaches its saturation point?
A change of state will occur.
What happens to a substance's temperature as it god through the change of state?
Its temperature remains constant.
What is the name of the change of state that happens when lead is heated until it turns into a liquid?

What change of state happens when something vaporizes?
what change of state happens when something melts
When rocks are affected by weathering and erosion they change into the following?
state of matter of inner core
What is the change of state when magma crystallizes from igneous rock?
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.

Gas to liquid.
Adding or removing what makes substances change from one state to another?
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
What happens during state of change?
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
What happens when a physical reaction occurs?
For example, the change in the state of matter.
What happens to a substance's temperature as it god through the change of state?
