Steam is just water in the gaseous state.

Steam is merely water vapour at a temperature equal to or greater than the boiling point. We cannot see water vapour; for the same reason, we cannot see steam.
When water is heated in a vessel with a nozzle, a cloud forms as the hot water vapour issuing from the nozzle mixes with the colder surrounding air. Such a cloud is popularly, although incorrectly, called "steam". We cannot see steam, so what we can see is not rightly called steam. Call the cloud what you like, but just remember that it is composed of water droplets not water vapour. Like mixing cloud in meteorology, it is the mixing of moist air masses with different characteristics that yields such a cloud. If you heat the nozzle with a gas torch the cloud will soon disappear. Yet, water vapour is still issuing from the nozzle.
water is in liquid phase and steam is in vapour phase.
steam is wet, saturated or superheated.
If you have water in a pan on a heat source. Heat rises. So the surface of the water is hotter then the the water under the surface. You are seeing the surface vaporizing before you see the lower water boil. Which the boiling action is caused by the water at the bottom at some point is hotter then the above water.
You are actually seeing steam in bubble-form rising to the top to be released.
Water will be converted into steam at 100 degree centigrade at atmospheric pressure.
If water contained in a close vessel , then the boiling temperature will be more at higher pressure.
so, some boilers are high pressure and some are low pressure.

Both are same, except difference in the state. Steam is gas and water is liquid. You heat water above 100 degrees celcius to get steam. This is known as evaporation.
No offence, but can't believe you don't know this. Or maybe your question is not specific enough?

What are you looking for?both are h2o, water is a liquid,steam is a gas.steam also contains more energy than water,as once reaching conversion point, 100 deg Cel one ltr off water would,have expanded 22,000 times,to turn into a gas.If you reverse the opp and put h2o below 0 deg Cel,turning the liquid into a solid , again increasing the energy content than that of water at 0 Deg Cel, and again expanding it!

steam is the gassy form of water being dissolved because of all the heat and water is a liquid

Nothng, really. They are the same. Steam is water in a "gaseous" state....over 212 degrees..
Water is anything else.... degrees do not matter, liquid, solid,etc

steam is just heated water that is a gas instead of a liquid.

steam is water but at a higher temperature where the molecules are vibrated more rapidly and become lighter than air

steam is water in another state difficult to make in Alaska but easy to make in Arizona

steam is water boiled that become steam, water is water
