The molecules in a solid are held together by short invisible bonds. A way to think about these bonds is that they slowly stretch as they move towards gas form. So in a solid the bonds are stronger and shorter, without them being held in such close proximity to each other they wouldn't be able to hold there shape, resulting in a more liquid form.
Now in short, it is so the invisible bonds can more easily control the molecules in the object.
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.
Bare covalent molecules are typically liquids or gases because they have weak intermolecular forces between the molecules. These weak forces are not strong enough to hold the molecules closely together in a solid form, leading to a lower melting point and boiling point. As a result, bare covalent molecules tend to exist as liquids or gases at room temperature.
The molecules of liquid are loosely packed but they can not move out of the container their movement is restricted to the cotainer only but the molecules of gases can move freely without any restriction.
When gases turn into liquids, it is called condensation. This process involves cooling the gas down to its condensation point, which causes the gas molecules to come together and form a liquid.
The main difference is the amount of space between the molecules. In gases, molecules are far apart and move freely, while in liquids, molecules are closer together but can still move past each other. In solids, molecules are tightly packed and have little freedom to move.
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.
in a liquid the molecules are closer together in a gas all bonds are released and the molecules sperate indeffinately
No, atoms are not closest together in gases; in fact, they are farthest apart compared to solids and liquids. In gases, atoms or molecules move freely and are spaced widely apart, resulting in low density. In solids, atoms are tightly packed in a fixed structure, while in liquids, they are closer together than in gases but still have some mobility.
Sound travels faster through liquids than gases because the molecules in liquids are closer together, allowing sound waves to propagate more quickly.
When molecules in liquids and gases are heated they move faster

in solids the molecules are rigid, hard to move, stuck together in liquids they are close together but can still move in gasses theyre far apart with alot of space between molecules, they can move very freely
after atoms and molecules of gases and liquids are heated, they sink?
If you think of density in terms of particles this becomes easier to remember. In which would the particles be closer together? A liquid, so the liquid is denser.
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.
Sound is transmitted by the molecules in a substance jiggling back and forth and passing on this energy to the molecules next to them. This happens the quickest when the molecules are closest together, which is a property of solids. The molecules in solids are packed in closer than they are in liquids and much more so than in gases, so sound travels much faster in solids.
Petrol is a liquid and does not easily compress because its molecules are already close together. When pressure is applied, the molecules can't be pushed closer, so the volume remains relatively constant. Liquids like petrol have more resistance to compression compared to gases.
