Question
What equations are essential for this law?

Answer
Hi Mary,

There is really only one equation for the second Law and it is

dS = dQ/T

Where S is the entropy (randomness) Q is the heat transferred and T is the temperature in K.
d is an very small increase.

The subject is very well covered in Wikipedia.

I hope this helps.

Best wishes.
Kevin
