To freeze 1 gallon of water, it requires approximately 144 BTUs. This is based on the latent heat of fusion, which is the energy needed to change water from liquid to solid at 32°F (0°C). Since 1 gallon of water weighs about 8.34 pounds, the total energy required includes the cooling of the water to its freezing point as well as the phase change.

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 BTUs per gallon of petrol?
About 114,000 BTU per US gallon.
How many BTU's per gallon of kerosine?

How many Btu's are in a gallon of fuel oil compared to a gallon of propane?
A gallon of fuel oil typically contains about 138,500 BTUs, while a gallon of propane provides approximately 91,500 BTUs. This means that fuel oil has a higher energy content per gallon compared to propane. Therefore, when considering energy output, fuel oil is more efficient in terms of BTUs per gallon.
How many therms to heat one gallon of water 50 degrees?
To heat one gallon of water by 50 degrees Fahrenheit, you need approximately 0.2 therms of energy. This is based on the fact that it takes about 8.33 BTUs to raise the temperature of one gallon of water by one degree Fahrenheit, totaling around 416.5 BTUs for a 50-degree increase. Since one therm is equivalent to 100,000 BTUs, the calculation gives you about 0.00416 therms per degree, resulting in roughly 0.2 therms for the total increase.
How many BTUs will it take to change 1 gallon of water at 32 degrees to ice at 32 degrees?
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.
How many BTUs does it take to heat 390 gallon tank of water from 60 degrees to 248 degrees?
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.
How long does it take 1 gallon of water to freeze at 32 degrees?
There is no standard length of time that it takes for a gallon of water to freeze. The amount of time it takes for a gallon of water to freeze can vary depending upon many different things such as temperature.
How many btus does it take to heat up one gallon of water?
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.

How many BTU are needed to reduce 50 gal of water 20 Deg F?
To calculate the BTUs needed to reduce the temperature of 50 gallons of water by 20°F, you can use the formula: BTU = gallons × weight of water (8.34 lbs/gallon) × temperature change (°F). For 50 gallons, that would be 50 × 8.34 × 20 = 8,340 BTUs. Therefore, you need approximately 8,340 BTUs to achieve this temperature reduction.
How many BTUs are in a gallon of propane?
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.
