WebDec 21, 2024 · 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. Specific Latent Heat of Fusion & Vaporisation Lecture 1.
