The Latent Heat of Fusion Calculator is a valuable tool used in physics to determine the amount of energy required to change the state of a substance from a solid to a liquid without changing its temperature. It operates on a straightforward formula:
Formula of Latent Heat of Fusion Calculator
Q = m * Lf
Where:
Q is the latent heat of fusion (in joules) m is the mass of the substance undergoing fusion (in kilograms) Lf is the specific latent heat of fusion for the substance (in joules per kilogram)
This formula helps in quantifying the energy needed during the phase transition of a substance. It's particularly useful in various scientific experiments, industrial processes, and understanding material properties.
Useful Conversions and Information
| Term | Conversion/Information |
|---|---|
| Water Latent Heat | 334 kJ/kg at 0°C |
| Ice to Water | 333.55 kJ/kg at 0°C |
| Aluminum | 397 kJ/kg |
| Lead | 23 kJ/kg |
Understanding these values simplifies practical applications, eliminating the need for manual calculations each time.
Example of Latent Heat of Fusion Calculator
Imagine a scenario where 1 kg of ice needs to be converted into water. Using the formula with the specific latent heat of fusion for ice (333.55 kJ/kg), the calculation would be:
Q = 1 kg * 333.55 kJ/kg = 333.55 kJ
This means 333.55 kilojoules of energy are needed to convert 1 kilogram of ice into water.
