How to Calculate and Solve for Volume Free Energy | Phase Transformation
Last Updated on December 12, 2022
The image of volume free energy is represented below.
To compute for volume free energy, three essential parameters are needed and these parameters are Latent Heat of Fusion (ΔHf),
The formula for calculating volume free energy:
ΔGv = ΔHf(Tm – T)/Tm
Where:
ΔGv = Volume Free Energy
ΔHf = Latent Heat of Fusion
Tm = Melting Temperature of Solid
T = Temperature
Let’s solve an example;
Find the volume free energy when the latent heat of fusion is 7, the melting temperature of solid is 3 and the temperature is 11.
This implies that;
ΔHf = Latent Heat of Fusion = 7
Tm = Melting Temperature of Solid = 3
T = Temperature = 11
ΔGv = ΔHf(Tm – T)/Tm
ΔGv = (7)(3 – 11)/(3)
ΔGv = (7)(-8)/(3)
ΔGv = (-56)/(3)
ΔGv = -18.66
Therefore, the volume free energy is -18.66 J.
