Heat of Fusion Calculator

Formula

The formula to calculate the Heat of Fusion (Hf) is:

\[ Hf = \frac{q}{m} \]

Where:

\(Hf\) is the heat of fusion (J/g)
\(q\) is the total heat required to melt the solid (J)
\(m\) is the total mass of the material that was melted (g)

What is Heat of Fusion?

The heat of fusion is defined as the total energy per unit mass required to turn a solid into a liquid of a given material. It is a crucial parameter in understanding the thermal properties of substances and is used in various scientific and engineering applications.

Example Calculation

Let's assume the following values:

Total Heat Required (q) = 5000 J
Mass of Material (m) = 100 g

Using the formula to calculate the Heat of Fusion (Hf):

\[ Hf = \frac{q}{m} = \frac{5000}{100} = 50 \text{ J/g} \]

The Heat of Fusion (Hf) is 50 J/g.
