WebSuppose a bag full of ice (450 g) at 0.0 °C sits on the counter and begins to melt to liquid water. How much energy must be absorbed by the ice if 2/3 of it melted? What amount of heat is required to completely melt a 29.95-gram sample of H_2O (s) at 0° C? What is the enthalpy required to vaporize "63.5 g" of water at 100^@ "C"? WebDec 21, 2024 · To answer to this question, you need the equation: Q = Lice × m Q is the amount of heat needed to melt the ice, Lice is the Latent Heat of melting for ice, and m is the given mass of ice. Various tables of latent heats give us: Lice = 3.34 ⋅ 105 J kg m = 250g = 0.25kg. So: Q = (3.34⋅ 105 J kg) × (0.25 kg) = 83,500J = 83.5kJ
