Water that is boiling can only achieve 100 degrees Celsius (at sea level).
Once turned into steam it can achieve at lot higher temperature. (Super heated steam).
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
In the case where heat is being added to generate steam from a container of water, as long as there is water still in the container, the temperature remains constant. It takes energy for water to change state into steam and all of the heat added goes to performing this task so the temperature stays the same, 212 degF (100 degC) at atmospheric pressure. While the water is boiling, the steam is "saturated," meaning any loss of heat would cause some of the steam to condense back into water. Once all of the water has been boiled and changed state, any additional heat supplied will cause the temperature to increase and the steam is "superheated," that is above its saturation temperature.
AnswerSteamAdded:Steam causes more severe burns as compared to boiling water because steam contains more heat (i.e 40.6 kJ/mol condensation heat) then boiling water, both at the same temperature 100 oC.From that condensation is momentanous when in contact with skin, after being liquefied it behaves the same as boiling water: still 100 oC and cooling down is slower than condensation.
If the steam is superheated, then yes - it can be used to boil water. If the steam is at the saturation point however, the most you could achieve would be to heat the liquid water to the boiling point while condensing some of the steam.
Yes, steam is an example of gas because, in simple terms water boiling then gaining enough heat to evaporate makes steam. Since anything going from a liquid to the next is a gas, this makes steam a gas because it evaporates.

Because steam is hotter than boiling water.
A steam engine is a heat engine. A steam engine uses boiling water to produce mechanical work. It uses the steam from the boiling water as its working fluid.
Steam boilers work by boiling water to generate steam. The steam then is used to heat the engine.
The steam density refers to the density of steam at a given specific heat and boiling point.
steam is the gaseous transformation that takes place on heating water to its boiling point.Steam will give you more burn than the water boiling at 100 c as it has the latent heat of vapourisation in addition to the heat of fusion.Basically it has more heat content in the steam state than boiling water state.
Superheated steam is steam at a temperature higher than water's boiling point
heat it to a boiling point and it will turn to steam and evaporate.

steam causes severe burns because of change of state i.e. liquid to gas with effects our skin. where as boiling water is only liquid which is hot but it does not effect the skin more than water.Thus higher the temperature of steam as compared to water. cause more severe burns than boiling water
The boiling point of water is 100 degrees celsius. The water will evaporate at boiling point. By the way what do you mean "what happens to the temperature of boiling water" if you think about it, it does not make sense.
Steam has more heat capacity than boiling water by its condensing to liquid and after that it'll conduct heat better as being liquified.Added:Steam causes more severe burns as compared to boiling water because steam contains more heat (i.e 40.6 kJ/mol condensation heat) then boiling water, both at the same temperature 100 oC.From that condensation is momentanous when in contact with skin, after being liquefied it behaves the same as boiling water: still 100 oC and cooling down is slower than condensation.
