It takes 970 B.T.U.s to change one pound of water to a gas at any temperature. So it takes 970,000 B.T.U.s to change 1,000 pounds of water to a gas. "Steam" is generally considered water when it is a "gas."
When water evaporates from your skin, from a glass, or from the ocean at it always takes with it 970 B.T.U.s per pound of water. This is true even if the water temperature is just 70F. It is not necessary for water to be heated to 212F to evaporate. Water will evaporate at any temperature so long as it is exposed to air.
Whenever water evaporates (turns into a gas) it takes with it 970 B.T.U.s per pound. If you want to boil water, it takes one B.T.U. for each degree F you raise the temperature of water till you get to 212F. Water will not get hotter than 212F at sea level until every last bit of it has turned into a gas.
The heat to transform liquid water to gas water is called the heat of vaporization, or the latent heat of evaporation. The heat to liquify water from ice is called the heat of crystalization. The heat needed to be removed from water to turn it into ice is called the heat of solidification.
Because the water's heat of vaporization is so high, water has cooling power. Outdoor misters are based on this principle. They spray a super fine mist of water into the air. Because the water in this super fine mist has a very large surface area, it evaporates at normal ambient tempemeratures. Air is hydroscopic. That means air naturally absorbs water. The less water or humidity there is in the air, the faster this process takes place.
Whenever matter changes state from solid to liquid or liquid to gas, it takes heat to break the chemical bonds.

How many btus does it take to turn water into steam?
It takes approximately 970 BTUs to convert one pound of water at 212°F (100°C) to steam at the same temperature.
How many BTU will it take to change 10 pounds of ice at 20 degrees to steam at 220 degrees?
To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
How many btus does it take to raise 1 pound of water at 32 degrees to 212 degrees of steam?
It takes 180 BTUs to raise 1 pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit to convert it completely into steam. This change in temperature includes heating the water from its freezing point to boiling point, then undergoing phase change from liquid to gas.
How many BTU's does it take to convert 1 lb of water at 212 degrees F to 212 degrees steam?
It takes 970.4 BTUs to convert 1 lb of water at 212°F to 1 lb of steam at 212°F. This process is known as the latent heat of vaporization.
How many btus will it take to raise 50 pounds of ice at 32 degrees to water at 160 degrees?
To raise 1 pound of ice from 32°F to water at 32°F it requires 144 BTUs. Since you have 50 pounds of ice, you would need 50 * 144 BTUs to raise the ice to water at 32°F. To further raise the water from 32°F to 160°F, you would need an additional amount of BTUs based on the specific heat capacity of water.

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 does it take to raise the temperature in a 40 gallon water heater 60 degrees F?
To calculate the BTUs needed to raise the temperature of a 40-gallon water heater by 60 degrees Fahrenheit, you can use the formula: BTUs = gallons × temperature rise × 8.34. For a 40-gallon heater, it would be 40 gallons × 60°F × 8.34 BTU/gallon°F, resulting in approximately 20,016 BTUs. Therefore, it takes about 20,016 BTUs to achieve that temperature increase.
How many btu to heat 1600 sf?
On average it takes about 1,600 BTUs to heat 50 square feet. Multiplying 50 by 1600 equals about 80,000. Therefore, the heating plan of 1,600 square foot are would take about 80,000 BTUs.
