Energy needed to heat up a substance
WebFeb 1, 2024 · The required watts to heat the water in that time should be 278.75. You can check the results with the formula: Ẇ = Q/Δt = (4181.3 J/kg·K × 1kg × 40K)/600s = … 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.
