1. The latent heat of fusion is about 264 289 kJ / kg. 2. You'd also need to think about heat of vaporization and heat of fusion . 3. How the hell are we missing the heat of fusion for such a common substance? 4. As it does so it absorbs an amount of heat energy called the latent heat of fusion . 5. The latent heat of fusion is the enthalpy change of any amount of substance when it melts. 6. :: The L's in part 3, stand for latent heat of fusion / vapourisation. 7. Based on the heat of fusion being, 1 tonne of refrigeration = 13, 954 kJ / h =. 8. Regular table salt has a melting point of 800 �C and a heat of fusion of 0.52 kJ / g. 9. Look at the specific heat of air versus the specific heat of water as well as the heat of fusion of water. 10. A high melting point results from a high heat of fusion , a low entropy of fusion, or a combination of both.
