There are 3.966 BTU in a kilocalorie (kcal), and 1 kcal raises 1 kg of water 1 degree C, but to work through it:
1 BTU raises 1 pound of water 1 degree F, and 1 kg = 2.20 pounds, therefore:
2.20 BTU raises 1 kg of water 1 degree F, and 1 litre of water weighs 1 kg (basically), therefore:
2.20 BTU raises 1 litre of water 1 degree F, and a 1 degree change in F equals 5/9 degree C, therefore:
2.20 BTU raises 1 litre of water 5/9 degree C, therefore:
3.96 BTU raises 1 litre of water 1 degree C.
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
2250
That will completely depend on how much water there is.
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.

There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water
One measure does not directly translate to another. A BTU is the amount of heat that it takes to raise the temp of one pound of water by one degree F. A burning match, and a burning fireplace may both be at 650 degrees, but the fireplace gives off more heat (more BTUs)
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
1 btu raises 1 lb water 1 degree F from 62 to 63 degrees. generally 1 btu/lb/degree F x 20 degrees F difference x 15 lbs = 300 btus specifically the heat of the liquid at 100F is 67.97 btus and at 120F = 87.92 btu 87.92 - 67.97 = 19.95 btu 19.95 x 15 lbs. = 299.25 btus to be more accurate
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
The specific heat of water is 1 BTU per pound per degree Fahrenheit. There are 8.3378 lbs/gallon at 60 degrees, which equals 3251.742 pounds of water. The number of BTUs to raise it 188 degrees is then 611,327.496 BTUs.
It depends on the volume of the room.
From high school science class; it takes 144 BTUs to melt a pound of ice. That takes it to 32 degrees F. To then raise the temp to 72 deg., would take about 40 more BTUs.
