How much energy does it take to heat water from 32 deg f to 132 deg f?

1 BTU (british thermal unit) of heat energy will change the temperature of 1 pound of water by 1 degree Fahrenheit. If you are talking about 1 pound of water, since this is a change of 100 deg f, it would require 100 BTU. 2 pounds require 200 BTU. 3 pounds require 300 BTU. etc.

How many btu to raise air temperature 1 deg?

It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.

How many Btu's are needed to bring lbs of ice from - degree F to degree F?

Depending on the mean temperature of the ice, it will require between 0.463 and 0.504 BTU's to raise the temperature of 1 lb. of ice for each deg. F. So, 5 lb of ice raised from 3 deg.F to 10 deg.F will require 5 x (10-3) x ~0.504 = ~17.64 BTU.

How long to heat a 25000 gallon inground pool with gas heater?

{Sigh} I hate English units. A BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * heat capacity * change in temperature. A gallon of water weighs about 8 lb, so you're talking about 500,000 gal * 8 lb/gal = 4 million pounds. The constant c for water, by the definition given above is 1 Btu/lb-deg F. So Q = 4 million pounds * 1 Btu/lb-degF * 32 deg F = 128 million BTU Note: 500,000 gal should be changed to 1250 gal or 3.2 million BTU?
