WebLatent Heat of Sublimation. Latent heat formula: Two formulas depend on the phase or temperature to calculate latent heat or energy. E = m × L ( For phase change). Q = m × c × ΔT ( For temperature change ). Here, E & Q is the energy for a state change, and m (kg) is mass. L is the specific latent heat (J/kg) & c is the specific heat capacity. WebExperiments show that the heat transferred to or from a substance depends on three factors—the change in the substance’s temperature, the mass of the substance, and … WebThe first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant. Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed. First Law of Thermodynamics: Euniv = Esys + Esurr = 0. tow song
