The specific heat capacity of water between 25 C and 100 C is 4.1813 J / (g*K).
Beyond 100 C, the heat capacity of water is 2.080 J / (g*K)
So, it take 4.1813 joules of energy to heat 1 gram of water 1 degree Celsius (Kelvin).
Therefore, in order to heat 22 g of water from 25 C to 100 C (75 C), it would require:
4.1813 * 22 * 75 = 6899.145 J
And, to heat 22 g of steam from 100 C to 125 C (25 C), it would require:
2.080 * 22 * 25 = 1144 J
The combined amount of energy required would be:
6899.145 + 1144 = 8043.145 J

What is the steam point of the Celsius scale?
at 100 degrees liquid water will go to steam and steam will go to liquid water
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 is the difference between btus and joules?
1 BTU is the energy required to heat 1 pound of water by 1 degree F. 1 Joule is defined mechanically, but in thermal terms it is 1/4.2 of a calorie (4.2 Joules/calorie), and 1 calorie is the energy required to heat 1 gram of water by 1 degree C. In fact 1 BTU = 1055 Joules.
What is water at 213 degrees Fahrenheit?
Water is vapor or steam at 213 0F at normal pressures.
When 1 gram of water at 0 degrees Celsius freezes to form ice how many total joules of heat are lost by the water?
It's necessary to remove 540 calories from a gram of water in order to freeze it. That's about 2260 joules. The amount of energy used by a freezer to do this depends on the efficiency of the freezer.
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
15480.80
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.
How much heat in joules is required to convert 92g of ice at 0.00 degrees Celsius to water vapor at 148 degrees Celsius?

How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?
4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.
How much thermal energy is required to boil 2.83 kg of water from 50c?
2830 g of water raised through 50 degrees C would use 2830 x 50 calories. But then to boil the water away to steam completely requires another 550 calories per gram, which is 2830 x 550 calories. To convert to Joules, use 4.2 Joules per calorie.
How much energy must be supplied to turn 1 gram of water at 100 degrees centigrade to steam at 100 degree centigrade?
Heat of vaporization of water is 2.26 x 106 joules per kg. Therefore 1 gram of water will need 2.26 x 103 joules.
How much energy would be required to vaporize 28 grams of water?
At standard pressure a gram of water at 100 degrees C requires 550 calories to convert it into steam at 100 degrees C. Therefore, 234.5 grams requires 128975 calories, or 541700 Joules.
How many watts of heat to raise 55.32 gallons of water to 160 degrees?
A watt is a unit of power: what is required is probably the amount of energy - which is measured in joules.
Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
How much heat is required to produce 1kg of wet steam at 350 kilopascals from water at 20 degrees Celsius if steam is 95 percent dry?
It equals one kilpod.
If you wish to heat water from thirty degrees to one hundred degrees how much heat will be required?
70 calories per gram. (The specific heat capacity of water is 1 calorie per gram per degree C.) This could be converted into Joules if necessary using the conversion factor of 1 calorie = 4.18400 Joules.
How much energy is required to raise 21kg of water by 2 degrees Celsius?
21 Kg = 2100 grams to rise the temperature of this amount of water by 2 degrees Celsius you need 2*2100 = 4200 calories or 17572.8 Joules.
