How much heat energy is needed to convert 50 kg of water at 80 degrees Celsius to steam at 100 degrees Celsius?
539 calories per gram for heat of vaporization plus 1 cal/gram/degree C 100 degrees C - 80 degrees C = 20 degrees C (539 calories + 20 calories) X 50 kg X 1000 gm/kg = 27950000 cal = 27,950 kcal
How many joules of energy are necessary to heat the steam from 100.0 degree c to 114.0 degree c?
That completely depends on how much steam there is. (mass)
How many joules of energy are necessary to heat the steam from 100.0 AC to 114.0 AC if the specific heat of steam is 2.01 Jg AC?

How many joules are needed to change 219.70 g of water at 72.7 C to steam at 100 C?
This value is 22,418 kJ.
Why steam is more dangerous than boiling water?
steam scalds are more serious than boiling water scalds because steam when condenses onto the more cooler skin, it loses latent heat of vaporization (to become water at 100 degrees Celsius) also it loses thermal capacity to become equal to the temperature of the skin (37 degrees Celsius). boiling water loses only thermal capacity as it cools down to 37 degrees Celsius from 100 degree Celsius.
How much heat energy will be required to lower the temperature of 2.67kg of steam from 282 degrees Celsius to 105 degrees Celsius?
You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
How many joules of energy are needed to heat 25.0 grams of steam from 100.0 degrees Celsius to 29.25 degrees Celsius?
Use this formula. q(in Joules) = Mass * specific heat * change in temperature I will use specific heat of water at 25 C. You can look up specific heat of steam. You say " heat to " so I assume you have final and initial heat backwards. q = 25.0 grams H2O * 4.180 J/gC * (100.0 C - 29.25 C ) q = 7393 Joules
How much heat energy is needed to change 10 kg of water at 50 degree celsius to steam at 120 degree celsius?
4.2 × 105 J
How much heat is released when 12.4 g of steam at 100 degrees celsius condenses to water at 100 degrees celsius?
The latent heat of condensation of steam is 2260 Joules per gram (539.3 cals/g). So the amount of heat released by 12.4 g = 12.4*2260 Joules = 28,024 Joules or 6687 cals.
Why would Steam at 100 degree celsius burn worse than that of liquid water AT the same temperature?
As the steam comes in contact with the skin, it becomes water, and releases more energy (about 2188 joules per gram) on contact than water at the same temperature.
What has the more heat energy at 100 degrees Celsius water or steam?
steam. It has to go through a phase change, which takes additional energy to get there.

How is the steam used to produce electricity?
A 300 grams of water takes about 90 seconds to boil in a 2 kW kettle, so that is 2000 watts x 90 seconds which is 180,000 Joules of energy. But to convert that water completely into steam requires an extra 300x550x4.2 Joules, which is nearly 700,000 Joules. So converting it to steam takes 4-5 times as much energy as boiling it. That is why it takes a while for a kettle to boil dry.
