Technically 1 BTU equals 1,055.05585 joules
This is the amount of energy required to raise 1 pound mass of liquid water at 1 atmosphere pressure by 1 degree Fahrenheit from 60 to 61 degrees.
You can say "approximately" 150 BTU provided you have liquid water and the 15 degrees change keeps it liquid.
When water gets to 212 degrees it begins to boil and the temperature (of pure water) will stay that way until it is boiled away regardless of how many BTU you add to it.
Also if the water is under pressure (ie a pressure cooker) the 1 BTU rule does not apply.
Likewise at freezing temperatures this rule won't apply nor in vacuums.
When talking about energy used to heat water a curve based on temperature and pressure that looks like a "bell curve" is used.
By Selecting a pressure on the curve you can determine the amount of energy needed to change temperature. This internal energy is referred to as enthalpy not to be confused with entropy.

How many btus does it take to raise of 5 pounds of water to 5 degrees Fahrenheit?
25
What is the BTU required to raise the temperature of 10 pounds of water from 50 degrees to 70 degrees?
200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200
How much heat is required to raise the temperature of 10 pounds from 50 to 70 Fahrenheit?
The answer depends on the unidentified substance whose temperature is to be raised.
How many Btus will it take to raise 10 pounds of Ice from -5 to 220 Degrees?
If you're in Celsius, 13459.5 Btu's. If you're in Fahrenheit, 12632.5 Btu's.
How many btu to raise the temperature of water from 60 to 120 degrees?
That's going to depend on how much water you're responsible for. Teacup at 60 degrees . . . very few BTU. Swimming pool at 60 degrees . . . many more BTU. It's also going to depend on whether you're talking about Celsius or Fahrenheit degrees. Fahrenheit degrees . . . fewer BTU. Celsius degrees . . . more BTU. (Also, the water will escape as you pass 100.) In general, one BTU is approximately the energy required to raise the temperature of 1 pound of water 1 degree Fahrenheit. You can take it from there, when you reach the job site and determine the exact scope of the work.
How many calories are required to raise the temperature of 1 g of water by 5 degrees C?
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
How many btu's would be required to raise 45 pounds of water 18 degrees Fahrenheit?
A british thermal unit (btu) is the amount of heat required to raise 1 pound of water 1 degree fahrenheit. How many btu's would be required to raise 45 pounds of water 18 degrees fahrenheit?Solution 44430Amount of heat= {(1 btu) / [(1 lb)(1 F)]} * (45 lb) * (18 F)= 810 btu
How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
15480.80
How much energy is required to raise 160 cfm of air from 10 to 170 degrees f?
The amount of energy that is required to 160 cfm of air from 10 to 170 degrees F is 200 btu. T he formula is weight x specific heat x temperature difference so we have10 pounds x 1.00 x 2010 for 10 pounds of water.
How many Btus will it take to raise 10 pounds of water from -5 to 220 Degrees?
2250
How much energy is required to raise 3 kg of aluminum from 18 degrees C to 23 degrees C?
13,455 J
What mass of water can be heated from 25 degrees celsius to 5 degrees celsius by the addition of 2825 joules?
None. Changing water from 25 degrees C to 5 degrees C requires heat to be REMOVED, not added!
