The observation about gases that proved molecules can move is their compressibility. This is further corroborated by the Brownian Motion theory.
When molecules in liquids and gases are heated they move faster
Yes. Gases move fastest, followed by liquid, while solids are the slowest.
Molecules move around easiest in gases because they have high kinetic energy and are not closely packed together, allowing them to move freely and rapidly. In gases, molecules have more space to move around compared to liquids and solids, where intermolecular forces restrict their movement.
When heat is added to liquid, the liquid molecules move faster They can move out of the container
The molecules in side move or spread apart
Particles move most rapidly in stream rather than in boiling water.This is because the molecules of gases are loosely arranged than the molecules of liquids.So there will be more free space for the molecules to move in gases than in liquids.
Molecules in the gaseous state are totally free to move around due to the weak intermolecular forces present in gases. This allows individual molecules to move independently and in random directions.
Yes, gases can both expand and contract. When heated, gases expand as the molecules move more rapidly, increasing the pressure and volume. Conversely, when cooled, gases contract as the molecules slow down, decreasing the pressure and volume.
Molecules actually move faster in liquid because they have more space between them to move about. That's why liquid can flow, and a solid cannot. =)
The gas molecules move about randomly.
Yes. They are able to flow.
In solids, molecules are tightly packed in a fixed arrangement. In liquids, molecules are more loosely packed and move freely. In gases, molecules are spread out and move independently of each other.
