How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
How many btu to raise air temperature 1 deg?
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 pound of -4 degree F ice to 284 degree F steam how many BTUs does it take?
1320 btu`s
How many Btus will it take to raise 10 pounds of water from -5 to 220 Degrees?
2250
How many BTUs does it take to raise the temperature of water from 32 degrees to 300 degrees?
That will completely depend on how much water there is.
How many btu's in office water-cooler?
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
How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
What is 650 degrees in BTUs?
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)

BTUs to melt one pound of ice?
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.
1 pound of -4 degree F ice to 284 degree F steam how many BTUs does it take?
1320 btu`s
How many btus does it take to raise of 5 pounds of water to 5 degrees Fahrenheit?
25
How many Btus will it take to raise 10 pounds of water from -5 to 220 Degrees?
2250
How many btus are required to change one pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.
How many BTUs will a 100 pound propane tank produce?
A 100 pound propane tank has a capacity of 2,160,509 BTUs
How many BTUs does it take to raise the temperature of water from 32 degrees to 300 degrees?
That will completely depend on how much water there is.
