1 BTU = heat corresponding to change in temperature of 1 pound of water by 1° Fahrenheit.
Weight of 1 gallon of water = roughly 8.33 pounds
Heat corresponding to change in temperature of 1 gallon of water by 1° Fahrenheit = 8.33 BTU.
But it doesn't take that, i.e. you don't have to supply it. You're talking about lowering the
temperature, so you're just allowing the water to cool on its own. As it does, it releases
8.33 BTU of heat, which you can then collect and take away to use somewhere else.

There are no units for the temperature. The temperature change could be 230 Celsius degrees or 170 Fahrenheit degrees (94 Celsius degrees). In fact they could be in less commonly used units: eg Reaumur.
100 BTU if it's Fahrenheit
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
Heating a gallon of water by one degree Celsius requires around 8,337 BTUs (British Thermal Units) of energy. Since 1 cubic foot of natural gas produces about 1,031 BTUs, you would need roughly 8 cubic feet of natural gas to heat a gallon of water by one degree Celsius.
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.
To raise the temperature of 1 gallon of oil by 1 degree Fahrenheit, it typically requires about 1,800 BTUs. This value can vary slightly depending on the specific type of oil, but 1,800 BTUs is a commonly accepted estimate for heating purposes.
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
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.
About 114,000 BTU per US gallon.
BTU is an abbreviation for British Thermal Unit. This represents how much heat or energy is required to increase the temperature of 1 lb of water by 1 degree Fahrenheit. Gasoline, on average, creates between 115,000 and 125,000 BTUs. In contrast, ethanol creates about 75,000 BTUs.
A gallon of kerosene typically contains about 135,000 BTUs of energy. At a burn rate of 30,000 BTUs per hour, a gallon of kerosene would last approximately 4.5 hours (135,000 BTUs ÷ 30,000 BTUs/hour = 4.5 hours). However, actual burn time can vary based on factors such as efficiency and burner design.
One gallon of kerosene will produce 134,000 BTUs of energy when burned.
Depends on the BTUs of the heater.
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
