SUMMARY
The calculation of energy required to melt 1mm³ of carbon steel at an initial temperature of 20°C involves two key components: heating the steel to its melting point of 1535°C and adding the latent heat of fusion. The formula Q = C_v * (1535 - 20) is insufficient as it neglects the latent heat necessary for the phase change from solid to liquid. Accurate energy calculation must include both the sensible heat and the latent heat of fusion to achieve the correct result.
