It's a physical change - more intermolecular bonds (bonds between different molecules) are formed due to the cooling of the matter, and the state of matter changes from liquid to solid. The chemical makeup of the lava does not change.
What else can I help you with?
A sentence with the word molten?
The molten hot lava was hardening.
What forms igenous rock?
The cooling, solidification, crystallization and hardening of molten magma or lava.
Hot lava cooling and hardening is an example of what in matter?
Hot lava cooling and hardening is an example of a physical change in matter, specifically a process called solidification or crystallization. This occurs when the lava loses heat energy to its surroundings, causing the liquid rock to solidify and form solid rock structures.
What type of rock is igneous?
Igneous rocks are formed by the hardening of molten lava from a volcanic erruption. These rocks are also categorised by two types. One that is formed by rapid hardening / solidifying of lava eg. Granite and one that is formed by slow hardening eg. Basalt. These rocks have high density, strength and are bulky.
What is the difference between lava and molten rock?
Lava refers specifically to molten rock that flows on the surface of the Earth during a volcanic eruption. Molten rock, on the other hand, is the hot, liquid rock below the Earth's surface that has not yet erupted. Essentially, all lava is molten rock, but not all molten rock is lava.
How does lava form rock?
From cooling and hardening
You are a metal and a liquid What are you?
Lava, or molten lava.
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 is a substance that can survive molten lava?
Most likely an igneous rock can withstand molten lava.
What is a product of the solidification of magma or molten lava?
A product of the solidification of magma or molten lava is igneous rock.
What are the streams of molten lava spilled out of a volcano called?
Streams of molten lava out of a volcano are called 'lava flows'.
How are lava and magma the same?
Lava and magma are both molten rock beneath the Earth's surface. The main difference is that magma is molten rock below the surface, while lava is molten rock that has reached the surface through volcanic eruption.
