When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
What Made liquid by heat?
When a substance is heated, it absorbs energy in the form of heat, causing its molecules to gain kinetic energy and vibrate more rapidly. Eventually, the substance's molecular bonds weaken, allowing the particles to move more freely and rearrange into a liquid state. This process is called melting.
What rock is formed by molten material?
a molten rock
What are molten substances that appear at the surface of earth?

They change into, or become, a igneous rock
Is pouring molten gold into a mold a physical change?
Yes, pouring molten gold into a mold is a physical change. The gold changes from a liquid state to a solid state as it cools down in the mold, but its chemical composition remains the same.
