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.
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
That means that your body temperature is lower than 37 degrees Celsius. It probably means you have been inactive for a while. 37 C or 98.6 F is the average body temperature, not a required temperature. You can raise it a bit with some vigourous exercise or lower it by relaxing.
Are you using wood, coal, oil, electricity , propane, natural gas WHAT is the BTU of the natural gas ( Varies from 900 -1,200 BTU per CU FT) and oil #2 can vary from 138,000 - 140,00 BTU per gallon) and how much are you paying per THERM=Also various countries and cities have different charges for fuel=

A watt is a measure of energy, which may or may not be heat, but heat is considered to be the simplest form of energy and is an easy way to compare amounts of energy. Another measure of energy that is easy to work with is a calorie, which is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree C. In these terms without special conditions, this applies only between 0 and 100 degrees C, because freezing and boiling make the equations much more complicated. A watt is approximately 86 calories, meaning that applied to a gram of water would raise its temperature by 86 degrees centigrade. A kilowatt is 1000 watts meaning that it could raise the temperature of that gram of water by 86000 degrees--at least theoretically, but that image is all but useless. So let's say that a kilowatt represents enough heat to raise the temperature of a liter (1000 g) of water by 86 degrees C.
To calculate the time taken to raise the temperature by 10 degrees, you would need to know the rate at which the temperature is increasing. This can be determined by dividing the change in temperature (10 degrees) by the rate of temperature increase. The result will give you the time it takes to raise the temperature by 10 degrees.
A heater can raise the temperature of a fish tank if needed
U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.
probably more than one second
Calculating Necessary Pool Heater Output Formula... Pool Gallons X 8.33 X Desired Temp. Increase / 24 Hrs. =Heater BTU'S Per Hour Required To Heat Up The Pool Example: 30,000 gallon pool @ 55 degrees, heated to 75 degrees 30,000 x 8.33 x 20 = 4,998,000 BTU'S / 24 hours = 208,250 Output BTU'S per hour The example above shows that 20' x 40' pool with an average depth of 5 feet with a heater producing an output of approx. 210,000 BTU's would require 24 hours to raise the temperature of the pool 20 degrees.

This is a pretty straightforward calculation. By definition, a BTU is the amount of energy required to raise one pound of water one degree F. But you have one gallon of water, which weighs approximately* 8.34 pounds. So, you'd need 8.34 BTU to increase one gallon of water one degree F. Note how the amount of time was not important. Whether you heat the water slowly or quickly doesn't matter. You will still require 8.34 BTU to raise the temperature of a gallon of water one degree F. * I say approximately because the weight of water varies slightly with its temperature. Water is at its densest at 4 degrees Celsius (39 degrees F). A gallon of water at temperatures above and below that value will weigh less.
The answer depends on the number of guppies. A few guppies can live in a 2.5 gallon tank or larger, temperature between 72 and 80 degrees Fahrenheit. Many people raise fancy guppies in 5.5 and 10 gallon tanks.
The most effective method for using a room heater to eliminate bed bugs is to raise the temperature of the room to at least 120 degrees Fahrenheit for several hours. This high temperature will kill the bed bugs and their eggs, effectively eliminating the infestation.
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
If the temperature reads 6 degrees in a cool room, I would recommend wearing warm clothing or layers to stay comfortable. It may also be a good idea to use blankets or a heater if available to raise the temperature in the room.
The temperature in any rain forest will hardly ever raise above 93 degrees Fahrenheit. The temperature is normally a constant 80 degrees.
