Which materials come out during a volcanic eruption? In which state of matter are these materials? Are these materials cool or hot? Why?
Answers
During a volcanic eruption, the primary material expelled by the volcanic mountain is lava.
Lava is extremely hot and molten.
Along with lava, the other components that rise are steam, ash, gaseous sulphur compounds and broken pieces of rocks.
All these materials are also very hot and have a heat radiating effect to long radii.
Answer:
The correct answers of the question are given below:
Explanation:
A volcano let's the following materials out during a volcanic eruption:
a) Lava
Lava is the molten rock material that is present inside a volcano in the form of magma before it exploded. The chemical composition of this lava depends upon the chemical composition of magma.
It is present in the molten or liquid state and is extremely hot.
b) Ash
These are tiny particles made up of rocks or glass, that are blown into the air by force of the eruption.
It is present in solid or semi-solid state and are extremely hot.
c) Gases
A volcanic eruption results in the release of various gases such as water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. These gases are present in gaseous state are also very hot.
All these materials, when get ejected from the volcano, are extremely hot due to the inner temperature of the volcano which is over 1000° C. They then cool down quickly as they are exposed to the atmosphere.
