Latent Heat of Fusion
Latent heat of fusion refers to the amount of heat energy required to change 1 kg of solid into a liquid completely at its melting point. This is a specific type of heat energy that is required for a substance to change phases from a solid to a liquid.
Explanation
When a solid substance is heated, its temperature increases until it reaches its melting point. Once the substance reaches its melting point, the heat energy being added is used to break the bonds between the molecules in the solid, allowing the molecules to move more freely and become a liquid. This process requires a certain amount of heat energy, which is known as the latent heat of fusion.
The latent heat of fusion is a specific amount of heat energy that is required to change 1 kg of a substance from a solid to a liquid at its melting point. It is a characteristic property of each substance and is typically measured in units of J/kg.
For example, the latent heat of fusion of water is 334 kJ/kg. This means that it takes 334 kJ of heat energy to melt 1 kg of ice into liquid water at 0°C.
Conclusion
In conclusion, the latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is a characteristic property of each substance and is typically measured in units of J/kg.
