This is the latent heat of vaporisation of water, which at standard pressure, is 539 calories (per gram).
6,520 Btus
Leaving aside the effects of pressure, yes, the temperatures are the same. But the amount of heat (thermal energy) per gram, is much greater for the steam.
All calculations below are assumed done with all materials (ice, water, and steam) being at normal atmospheric pressure. 3.0kg is 3000 gm. Heat required to raise temperature of ice from -10 degree celcius to 0 degrees celcius is 3000 x 10 cals. (A) The latent heat of fusion of ice is 80 cals per gm. So heat needed to melt 3000 gm of ice at 0 degrees celcius is 3000 x 80 cal. (B) The heat required to convert 3000 gms of water from 0 degrees celcius to 100 degrees celcius is 3000 x 100 cals. (C) The latent heat of vaporization of steam is approximately 540 cals per gm. Hence heat required to convert 3000 gms of water to steam at 100 degrees celcius is 3000 x 540 cals. (D) Now add (A) + (B) + (C) + (D) = 30000 + 240000 + 300000 + 1620000 cals. And that is = 2190000 cals = 2.19 X 10 to power 6 cals.
Assuming standard atmospheric pressure, 2260 kilojoules.

540 calories are needed to turn one gram of water at 100 degrees celsius to steam.
Water or steam at 100 degrees Celsius will kill some bacteria. Detergent or soap is needed to kill the ones that survive the hot temperatures.
Well, you seem like a very smart kid. Let me ask you something: if you had one pound of naiveness in one hand and one pound of idiocy in the other, which one weighs more? Let me tell you a secret: Its the same!
at 105 degreesCelsius,steam is still steam.at about 50,000 degrees Celsius,steam turns into plasma, the fourth state of matter.
Steam is boiled up water that is over 100 degrees centigrade
Use boiler to turn heat to potential energy in steam the run the steam through the turbine dynamo transform the energy in steam to electricity.
It has to give up quite a lot of heat. A pound of steam carries 940 btu's of heat that has to be transferred out to end up with one pound of water at the same temperature. It only takes 180 btu's to raise water from 32 degrees Fahrenheit to 212 degrees.
This is the latent heat of vaporisation of water, which at standard pressure, is 539 calories (per gram).
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
Use boiler to turn heat to potential energy in steam the run the steam through the turbine dynamo transform the energy in steam to electricity.
at 100 degrees liquid water will go to steam and steam will go to liquid water
