Nobody's gonna just give you the answer. What are your thoughts on it? Do you know what a thermodynamic potential is?

In simple terms

the U representation

$$U=U\left(S,\{X_{i}\}_{i=\bar{1,n}}\right)$$

then a thermodynamic potential is a Legendre transformation of the internal energy wrt one or more intensive parameters associated to S and the external extensive parameters...
