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 are required to raise the temperature of 15 pounds of water from 100 degrees fahrenheit to 130 degrees fahrenheit?
To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.
How many btus does it take to raise of 5 pounds of water to 5 degrees Fahrenheit?

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 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 btus are required to change 5 pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
To change 5 pounds of ice at 20°F to steam at 220°F, you will need to go through multiple phases: raise ice temperature to 32°F, melt ice to water at 32°F, raise water temperature to 212°F, and then convert water to steam at 212°F to steam at 220°F. The total heat required, in BTUs, is around 503 BTUs per pound of ice, which translates to about 2515 BTUs for 5 pounds of ice.
What is the BTU formula?
BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.
Is temperature measured in calories?
No, temperature is not measured in calories. Temperature is typically measured in degrees Celsius (°C) or degrees Fahrenheit (°F), while calories are units of energy related to the amount of heat required to raise the temperature of one gram of water by one degree Celsius.
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 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 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 btu's would be required to raise 45 pounds of water 18 degrees Fahrenheit?
To calculate the amount of energy required to raise the temperature of water, you can use this formula: Heat energy (BTUs) = weight of water (lbs) x temperature change (°F) x specific heat capacity of water. For water, the specific heat capacity is 1 BTU/lb°F. Using this formula, the amount of energy required to raise 45 pounds of water by 18 degrees Fahrenheit would be: 45 lbs x 18°F x 1 BTU/lb°F = 810 BTUs.
