gas
Sound will travel fastest through a solid because the molecules in a solid are closer together, allowing for faster transmission of sound waves. Liquids and gases have molecules that are more spread out, hindering the speed at which sound can travel through them.
When they are hotter.
Solid
Sound waves travel faster in solids than in a gas, because the molecules are more closely coupled together (it is a solid remember?) and are more densely packed than in a gas (where they are free to wander).
Gas molecules are spread apart farther than solid molecules. They also have more energy, making them move faster
Gas molecules a spread out father than a soilid. This is beacuase gas molecules have nmore energy which makes them move much faster than the molecules in a solid.
yes
sound can travel past in solid because the molecules of solid is tightly closed and next liquid the molecules of liquid not so far away to each other and the slower is gas but it can travel longer than solid and liquid because the molecules in gas are far way and can move freely that can travel longer...
It becomes a liquid. solid, liquid, and gas are relative terms defining the movement of molecules, solid moves slow, liquid faster, and gas the fastest. molecules move constantly.
Solid. Because it's more dense.
Molecules move fastest in a gas, then in a liquid, and slowest in a solid. In a gas, molecules have high kinetic energy and move freely, while in a liquid, molecules can slide past each other but are still somewhat restricted. In a solid, molecules have the least amount of kinetic energy and vibrate in fixed positions.
The speed of sound is faster in a solid than in a gas because the molecules in a solid are closer together, allowing sound waves to travel more efficiently through the material. The denser molecular structure in solids results in quicker transmission of energy, leading to a higher speed of sound compared to gases with more spaced-out molecules.
