That's going to depend on the temperature of the water before you heat it,
and on how hot you want it to be when you're done.
The average-size hot tub holds approximately 475 gallons of water. The earliest known hot tubs were calderas. Hot stones were used to heat the water.
About 15,360 gallons.
One cubic foot of water is 7.4805 gallons.
No gallons of water. Stone does not contain water
5 to 7 gallons of water to run a dishwasher on a normal cycle.
The answer depends on the material. Different fuels have different amounts of heat energy.
110 therms.
1.034 therms
0.00863 kg/s
1 BTU is 0.00001 therms.
It uses as many as you run through it, but who would want to heat hot water?
Under intense heat and pressure, the soft coal turns into hard coal.
1 million BTU = 10 Therms
The word deca- means ten, so there are ten therms in a decatherm.
The answer depends on the material. The number of therms in liquid nitrogen is pretty close to 0.
