To evaporate one gallon of water, approximately 1,200 British thermal units (Btu) are required. This is based on the latent heat of vaporization, which is the amount of energy needed to convert water from liquid to vapor without changing its temperature. Specifically, it takes about 970 Btu to vaporize one pound of water, and since one gallon of water weighs about 8.34 pounds, the total comes to around 1,200 Btu.

It takes 8.33 BTU to raise the temperature of water 1 degree F.
114,000 BTU/gallon
114100 Btu
For regular gasoline, 125,000 BTU per US gallon
140,000 btu/gallon, nominal
To calculate the BTU needed to heat 10 gallons of water from 32°F to 212°F, you can use the formula: BTU = gallons × 8.34 (weight of water per gallon in pounds) × temperature change (in °F). The temperature change is 212°F - 32°F = 180°F. Thus, BTU = 10 gallons × 8.34 lbs/gallon × 180°F = 15,012 BTU.
In a gallon of gasoline, there is approximately 124,884 btu. BTU refers to British thermal unit. It is actually a traditional unit.
Propylene has a lower heating value of approximately 21,500 BTU per gallon.
No BTU are required in order to lowerthe temperature of water. All you have to dois place the water in an environment that is cooler than the water is, then stand backand watch the temperatue of the water drop while the BTU flow out of it.
