Molecules in the gas state move much faster than their liquid or solid states.
Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, or solid. At high temperatures and low pressures, the gas state is favored. When the molecule is in the gas state, it actually hits other molecules and bounces in random directions. A molecule moving as a gas is like a weightless Baseball hit inside a big empty room in outer space. The baseball bounces everywhere, and it moves very fast. In a gas, every time the molecule hits another molecule, it also bounces like the baseball.
In comparison, molecules in their liquid state can move, but they move much slower, because but they do not separate from each other. The movement of a liquid molecule is like you moving in a room packed with people. You can move, but you are always in contact with someone.
Even slower are molecules in their solid state. In fact, they do not move much at all. This time imagine that you are in a packed room, but now you are all sitting in connected chairs. You can wiggle your head, arms and legs, but you cannot leave the chair. Since you cannot leave the chair, and because the chairs are stuck together, you can not move your entire body to another place in the room. Using this analogy, molecules in the solid state are the slowest.

Molecules do not move faster in different states of matter, they simply have more space to move around in. To make something move faster you need kinetic energy (raise temp).
The state of matter with the fastest molecules is the gas phase. In gases, the molecules move randomly and have the highest average kinetic energy, resulting in faster speeds compared to liquids and solids.
A. air temperature rises and air molecules move faster
Basically, a solid is quite stationary. It doesn't move very much. Liquids have more energy, meaning that the particles move a lot freer. In a gas the particles are a lot further apart, meaning that they have a LOT more space to move. Solids can be made to move faster if you give it enough energy (ie, heat). The atoms then start vibrating faster, making spaces between the atoms. This is what happens (basically) when you melt something.

As molecules move faster, they cause friction, which increases the temperature of the molecules.
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)

A. air temperature rises and air molecules move faster
At higher temperatures, molecules move faster due to increased kinetic energy, leading to more collisions and higher rates of diffusion. In a solid state, molecules vibrate in fixed positions; in a liquid state, they move more freely but still have some interactions; in a gas state, molecules move rapidly and independently.
When heat is applied to water, the molecules excite and move faster, and change into a gaseous state.
Cause when you add energy it gets stimulated.
Molecules move faster when heated -- no matter what state they're in.

When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
