Want this question answered?
When matter is heated the molecules move faster and the speed becomes so great the molecules cannot hold together. The molecules fly apart and become a gas.
The speed doesn't change, it's just that the molecules are free to move around, rather than being restricted to a shape.
There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.
A rock, or any solid substance melts, it becomes less dense due to the heat exciting the molecules. They start to move and are bumping into each other at rapid rates, causing the fluid nature of the melted substance.
Sound travels fastest, and best through a solid. eg. steel
It depends which state of matter you are referring to -- solid, liquid or gas. Solid: molecules vibrate in place Liquid: molecules are moving faster than a solid but slower than a gas. gas: molecules are moving at a high speed hope this helps :)

The speed of sound is the fastest through a solid. You can calulate the speed by the formula distance and time. It is the fastest through a solid because the molecules are closer together than the other states of matter, so the reaction time is shorter.
The speed of sound is greater in solids. This is because the molecules in solids are closely packed. This allows sound to move faster.
Their speed - Kinetic Energy - increases as the solid melts.

There are three basic states of matter (not including plasma), they are solid, liquid, and gas. The thing or key that distinguishes them is the state of the molecules of those objects move. In solids, the molecules are packed together very tightly which gives its solid aspect. In a liquid the molecules are loose letting the object take a flowing shape (liquid). In a gas, the molecules are very loose and going everywhere giving it its gas-like appearance.

There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.
When water goes from a gas to a liquid, or a liquid to a solid, the water molecules have lower kinetic energy, and therefore they lose speed.
The speed would vary depending on where the molecules are found. Molecules in gas will move faster than they would in liquid.
