how many calories are in a cubic meter of air?(room temperature plz)

and by calories i mean thermal units, not the thing i'm trying to burn to lose weight, but the calories that heat 1 liter of water by 1 degree celsius. or BTU's can be used instead of calories.

uhhh, to tell the truth i'd like to know how much energy might be extractable from the normal room temperature of air.

The energy (heat) is the mass times the heat capacity times the absolute temperature. In other words, h=CmT

How you're going to "extract" this energy is up to you I guess.

a calorie is the energy required to heat 1 GRAM of water by 1*C. for a kilogram it would be a kilocalorie. try google. extraction of this heat energy to provide electricity isn't feasible so don't even think about it.

 

why don't you use SI units(joules in this case) then everybody will know what you are talking about wherever they come from

The available energy depends on the temperature of the reservoir into which you will eject the waste heat, and the mechanism you use to do work. heat engines

However if you are trying to extract it for the purpose of heating rather than doing work, as with a heat pump, it can be well worthwhile. Greater than 100% efficiencies can/should be obtained (not thermodynamic efficiencies, no laws are broken and entropy increases overall ).

what about a boiler that uses N2 as the boiling substance?
