At the boiling point, molecules begin to move from a liquid to a gaseous state. For individual molecules, this process (evaporation) can occur at temperatures lower than boiling.
*There is still additional energy required (called the heat of enthalpy) and there must be a nucleation point from which the molecules move. Lacking these, water can reach temperatures higher than the boiling point without becoming a gas.
Assuming they are non-volatile, solids in liquid water will remain in the water when it boils. This is the process of distillation, where the solids and non-volatile matter is separated from the water, and is left behind as the water evaporates off.
It evaporates if you leave it boiling for a long time
The particles have most energy in particles in steam. In a gas. the particles move more freely, Therefore, there is more energy in the steam. :D LOL
simply put. energy. take a kettle for example: heat energy is transfered to the water, exiting the particles and creating steam. liquid into gas.
imagine that you are heating a pan of tap water on a cooker and taking the temperature of the water with a thermometer every two minutes until after the water has boiled
It boils and becomes steam.
When a gas changes to a liquid or a solid the particles inside become more compact for example steam condences into warter and the particles become more compact but they arn't squished together ho ever in a solid the particles are very squished together. sublimation is what is happening.
Steam condences into water, water freezes in to ice, ice melts into water, water boils to steam
As the water heats up the pot you're boiling it in, the particles of the water receive more energy. The more energy the particles have, the faster they move and the farther they spread apart. When the water finally reaches 212 degrees Fahrenheit (100 degrees Celsius), its particles spread so far out that they make the transition from a liquid to a gas. Thus, making steam.
it gets hot
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.

the particles are given more energy.
Water boils at 100 and turns into a gas (steam)
It turns into a gas.
Actually when steam condenses it is loosing heat. As steam rises it cools and falls back down with gravity. I.E. a steam boiler heat system Boils water to till it turns into a gaseous mixture of water droplets and rises to a radiator to heat. As the radiator absorbs the heat from the steam It condenses and returns to the boiler through the same riser pipe to the boiler.

A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
When steam (or "water vapor") becomes water, the particles are condensating or becoming condensation. This is because the particles are cooling down, thereore not moving fast enough to remain a gas; so it becomes a liquid.
