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.

That will completely depend on how much water there is.

BTUs to Evaporate One Pound of WaterQuick Answer: Somewhere around 1000BTU/lb Long answer: It depends on the temperature of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are very few compared to the BTUs required to change the water from a liquid to a gas.One pound of steam contains 1150 BTUs. This is the energy you need to put into the water for it to evaporate if you start with water at 32F. If you start with water at 100F the water already has 70 BTU/lb so the BTUs required to evaporate the water when you start at 100F is 1150-70 = 1080 BTU and so on.You can get all this information in a steam table which can be found easily by searching the web.

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)

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.

One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.

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

6519.2 btus are required.

It takes about a thousand BTUs to turn a pound of water into a pound of steam, and that's how many BTUs must be removed to condense a pound of steam back into a pound of water.

212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU

Quick Answer: About 2,139 BTU/litre at the normal boiling point. Long answer: It depends on the temperature and pressure of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are very few compared to the BTUs required to change the water from a liquid to a gas. One litre of water weighs about 2.205 lb, and since both BTUs and lb are from the imperial set of units, we can make the rest of this explanation in terms of pounds and then just multiply by 2.205 when we get done. One pound of steam contains 1150 BTU/lb relative to liquid water at 32 °F. This is the energy you need to put into the water for it to evaporate if you start with water at 32 °F. If you start with water at 100 °F the water already has 70 BTU/lb so the BTUs required to evaporate the water when you start at 100 °F is 1150-70 = 1080 BTU/lb and so on. You can get all this information in a steam table which can be found easily by searching the web.

A BTU is the amount of heat required to heat or cool 1 lb of water 1 degree, water freezes at 32F so it should not require any more than 1 degree to be below freezing. There are 8lbs in1 gallon of water, so 8 BTU's will lower a gallon(8 lbs) 1 degree.

BTU: British Thermal Unit, the amount of energy it takes to raise one pound of water one degree Fahrenheit. In this case 500g(x aproximatly 8 pounds per gallon) or 4000 pounds x 70(the difference from 5 degrees to 75 degrees), which equals 280,000 BTUS
