How many Btu are required to change 600 pounds of water at 75 degrees F to steam at 212 degrees F?
1 BTU is required to raise 1lb of water 1 degree F in 1 hour. 212-75=137 degrees 600 lbs water x 137 degrees= 82,200 BTU's required to change 75 degree water to 212 degree water. To change 212 degree water to 212 degree steam it requires 970 btu's (latent heat of vaporization) per lb of water 970 btu x 600 lbs water = 582,000 btu Answer - 582,000 btu+ 82,200 btu = 664,200 btu's
How much heat is required to convert 1.00 kg of water at 100 degrees Celsius to steam at 100 degrees Celsius?
Assuming standard atmospheric pressure, 2260 kilojoules.
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 much heat is necessary to change a 52.0 gram sample of water at 33.0 degrees Celsius into steam at 110 degrees celsius?
Raise the temp of 52 grams of water from 33.0 C to 100 C = 52*67*4.184 = 14.577 kJConvert evaporate 52 g of water to steam without change of temp = 52*2259 = 117.468 kJRaise the temp of 52 grams of steam from 100 C to 110 C = 52*10*2.02 = 1.051 kJTotal energy required = 133.095 kJ = 31,811 calories or 31.811 kCal.
How 1 pounds of water converting into 1 pounds of steam?
2000 lbs
How much energy is required to change 80g of ice at -30 degrees celsius to steam at 140 degrees Celsius?
E = m c (delta)T
How many Btu are required to change 600 pounds of water at 75 degrees F to steam at 212 degrees F?

How many BTUs are required to change five pounds of ice at 20 degrees F to steam at 220 degress F?
The question cannot be answered because:the temperature scale being used has not been specified,There is no normal temperature scale in which you can have ice at 32 degrees and steam at 82 degrees without large changes in pressure. If changes in pressure are permitted then there is no simple formula to calculate the amount of heat (btus) required.
How many pounds of steam are required to heat one gallon of water?
it takes 2 pounds of it
What does water change to above 100 degrees Celsius?
Steam. Water boils at 100 degrees Celsius.
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 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.
How much heat energy would be required to bring a 15 kg block of ice from -20 degrees Celsius to steam at 120 degrees Celsius?
46389000 j
How much heat is required to convert 1.00 kg of water at 100 degrees Celsius to steam at 100 degrees Celsius?

Steam point of water?
Water turns to steam (or in other words, it boils) at 100 degrees Celsius or 212 degrees Fahrenheit.
