The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
A steam burn is an example of latent heat, because beside the heat released by the steam itself, a part of it condenses, turning into water, which in turn releases heat too.
No, steam is water as a gas.
the steam will give off a large amount of heat as it condenses.
No. Steam is warm water vapor. Heat is added or external energy that causes a rise in temperature.
Dry steam is superheated , meaning more heat has been added resulting in no liquid phase present and the heat of vaporazation has been surpassed adding to the total enthahpy of the vapor. Wet steam is much like the steam rising from a pot of boiling water.
The efficiency of a steam turbine is just the ratio of power out to power in, but if you want to be able to calculate it from the basic mechanical design, this is a specialised topic. In the link below is a general description of steam turbines, in the references and additional reading list there are some references that may help you.
A steam engine uses water, steam, and heat.
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy.

If you heat steam under pressure you get "superheated steam" under higher than original pressure

Nothing, a steam boat runs not on steam, but on a heat source GENERATING steam. this heat source is usually coal but could be wood or a fossil fuel.
steam (heat creates steam)
Steam is generated by heat from the combution of fuel in a furnace or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.
Heat it.... The heat will first convert ice into water and will then convert it into steam. You can heat ice in any kettle.....or saucepan.......
