Gases are compressible because their molecules bounce off of each other instead of sticking together. The molecules of solids and liquids stick together instead of moving freely.
Liquids and gases are amorphous (shapeless), viscous (can flow), and diffuse (have internal space) due to the movement of their molecules.
The particles of solids are very close and tight and are organised. The particles of liquids are randomly organised and are further apart. The molecules in gases are really far apart.
after atoms and molecules of gases and liquids are heated, they sink?
rise
When molecules in liquids and gases are heated they move faster
The molecules in side move or spread apart
All materials are formed from atoms.
Yes. They are able to flow.
Liquids and gases are made up of molecules that are free to move relative to each other. In liquids, the molecules are closer together and are able to flow, while in gases, the molecules are further apart and move around randomly. The main difference between the two is the level of intermolecular forces holding the molecules together.
Solids ---heat---> Liquids ---more heat---> gases
Solids and liquids are composed of atoms or molecules that are held together by various kinds of chemical bonds, whereas gases are composed of independently moving particles that are not held together, therefore they are free to expand.
Yes, all items contain - or are comprised from - molecules. Liquids , solids, and some gases are made from molecules, the rest are made up of Atoms.
When a substance is heated, the extra energy makes the atoms and molecules in the substance vibrate faster and, in liquids and gases, move faster. A measure of the average velocity of such movement is called temperature. The effect of this increased movement is to change the structure of the substance. The regular order of the atoms or molecules of a solid breaks down to form a liquid - this is called melting. Further heating makes the atoms or molecules move so fast that the interactive forces between them are overcome, and they become gases - in which the atoms or molecules are free to move throughout their enclosing volume. This is called boiling or evaporation.
