Try to answer these questions before determining the answers with the simulation. We suggest that you write down the reasons for your answers.

1. Given that the first law for a reversible process in a closed system is \(dU = TdS – PdV\), what physical property corresponds to \( \left( \frac{\partial U}{\partial S} \right)_V\)?
2. The first law for a reversible process in a closed system and the defintion of enthalpy can be combined to yield \(dH = TdS + VdP\) . What physical property corresponds to \( \left( \frac{\partial H}{\partial S} \right) _P\) ?
