### Open Systems & Pure Fluids

Perform 1st & 2nd analysis of heat and work interactions for open systems.Calculate process variables for pure fluids using equations of state, departure functions, and corresponding states.

### Pure-Fluid Calculations & Relationships

Calculate properties of pure fluids (e.g., vapor pressure, molar volumes, etc.) using correlations and equations of state. Calculate the properties of mixtures using ideal mixing properties and excess properties. Show relationships between pure-fluid properties (e.g., Clapeyron Equation) and determine partial molar enthalpies, volumes, and entropies from experimental data and from equations for excess Gibbs energy.
