## Phase Change Energy Formula

The following equation is used to calculate the Phase Change Energy.

Ephase = V*H

Variables:

- Where Ephase is the Phase Change Energy ((J))
- V is the volume of substance (m^3)
- H is the heat of fusion (J/m^3)

To calculate phase change energy, multiply the total volume of substance by the heat of fusion.

## How to Calculate Phase Change Energy?

The following two example problems outline the steps and information needed in order to calculate the Phase Change Energy.

**Example Problem #1:**

- First, determine the volume of substance (m^3). In this example, the volume of substance (m^3) is measured to be 4.
- Next, determine the heat of fusion (J/m^3). For this problem, the heat of fusion (J/m^3) is calculated to be 6.
- Finally, calculate the Phase Change Energy using the formula above:

Ephase = V*H

Inserting the values from above and solving the equation with the imputed values gives:

Ephase = 4*6 = 24 ((J))

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

volume of substance (m^3) = 4

heat of fusion (J/m^3) = 3

Entering these values into the formula or calculator above gives us: Ephase = 4*3 =** **12 (J)
