# How to Calculate and Solve for Solid-liquid interface | Nucleation Energies

The image above represents solid-liquid interface. To calculate solid-liquid interface, three essential parameters are needed and these parameters are Liquid Interface (Î³IL), Solid Interface (Î³SI)Â andÂ cosÎ¸.

### The formula for calculating solid-liquid interface:

Î³SLÂ =Â (Î³ILÂ – Î³SI)/cosÎ¸

Where:

Î³SIÂ = Solid Interface
Î³SLÂ = Solid – Liquid Interface
And then, Î³ILÂ = Liquid Interface

Let’s solve an example;
Find the solid-liquid interface when the liquid interface is 14, the solid interface is 2, and the cosÎ¸ is 4.

This implies that;

Î³IL = Liquid Interface = 14
Î³SI = Solid Interface = 2
cosÎ¸ = 4

Î³SLÂ =Â (Î³ILÂ – Î³SI)/cosÎ¸
So, Î³SLÂ =Â (14 – 2)/4
Î³SLÂ =Â (12)/4
Î³SL = 3

Therefore, theÂ solid-liquid interface isÂ 3.
