WebAn input of 334,000 joules (J) of energy is needed to change 1 kg of ice into 1 kg of water at its melting point of 0°C. The same amount of energy needs to be taken out of the liquid to freeze it ... WebJul 28, 2024 · Latent energy, to melt the ice at 0°C: Qp = L × m = (334000 J/kg) × 2 kg = 668000 J Sensible heat, to take the liquid water from 0 to 100°C: Qt = c × m × (Tf - Ti) = 4190 J/ (kg K) × 2 kg × (100°C - 0°C) = 838000 J. Latent energy, to evaporate the water at 100°C: Qp = L × m = (2264705 J/kg) × 2 kg = 4529410 J hikers paradise cameron
