Write a scientific explanation determining which unknown is the solid, which is the liquid, and which is the gas.

best answer I could find, hope it helps

Explanation:

Difference between Solid Liquid and Gases

Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids.

The intermolecular forces are stronger than gases but weaker than solids.

The intermolecular forces are practically non-existent. Thus, there is no definite volume.

Solids have a definite shape to them.Liquids do not have a definite shape.

Gases do not have a definite shape.

The intermolecular space between solids is absent.

The intermolecular space is moderate but present.

The intermolecular space is free-flowing and plenty.

The force of attraction between the molecules is incredibly high.

The force of attraction between molecules is pretty moderate.

There is no intermolecular force of attraction between the molecules.

They are incompressible.

Liquids cannot be compressed.

Gases can be compressed quite easily.

Solids have a definite shape and volume.

Liquids have a definite volume.

Gases have no definite volume.

Water

Explanation:

The Water can be a Solid State. (Ice)

The Water can be a Liquid State. (Water)

The Water can be a Gas State. (Steam)

Hope this helps! Please correct me if I'm wrong.

Unknown should be Water.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
