Phase Change Energy Calculator

Formula

The formula to calculate the phase change energy (Ephase) is:

\[ Ephase = V \times H \]

Where:

\(Ephase\) is the Phase Change Energy (J)
\(V\) is the volume of substance (m³)
\(H\) is the heat of fusion (J/m³)

What is Phase Change Energy?

Phase change energy is the amount of energy required to change the phase of a substance (e.g., from solid to liquid) without changing its temperature. This energy is calculated by multiplying the volume of the substance by its heat of fusion.

Example Calculation

Let's assume the following values:

Volume of Substance (V) = 2 m³
Heat of Fusion (H) = 334,000 J/m³

Using the formula to calculate the phase change energy (Ephase):

\[ Ephase = V \times H = 2 \times 334,000 = 668,000 \text{ J} \]

The Phase Change Energy (Ephase) is 668,000 J.
