Energy to heat air
WebPower-to-Heat (also PtH or P2H) [1] is a rather new name for the conversion of electrical energy into heat. [2] This can be done through conventional heating resistors, electrode … WebSpecific heat capacity of air is 1.006 kJ/kgC. Mass of air:density of air at 10C is 1.2466 kg/m3 and mass = density x volume = 1.2466 x 100 = 124KG. Temperature differential = 10C. energy needed = 1.006 x 124 x 10 = 1247 KJ. Power is energy transferred / second. That means, your 1000W space heater can transfer 1000J of energy / second.
