Metals - Latent Heat of Melting

Metals and their latent heat of fusion. The Latent Heat of Fusion is the heat supplied to a solid body at the melting point when it changes state from solid to liquid.

Latent Heat of Fusion Reference

The Latent Heat of Fusion is the heat supplied to a solid body at the melting point when it changes state from solid to liquid.

Latent heat of fusion is calculated as:

L = 1000 × L_mol / A

Where:

  • L = latent heat of fusion (kJ/kg)
  • L_mol = latent heat of fusion (kJ/mol)
  • A = atomic weight (g/mol)

Conversion: 1 kJ/kg = 0.23884 cal/g = 0.23884 kcal/kg = 0.4299 Btu/lbm
