Calculate Ideal Gas Thermodynamic Properties

Calculates thermodynamic properties of an ideal gas: entropy and internal energy. The ideal gas model is the simplest thermodynamic system and serves as a baseline for understanding more complex behaviors. Useful for theoretical benchmarks and educational purposes.

Use Cases:

Baseline models for market behavior
Theoretical efficiency limits
Educational thermodynamic concepts
Entropy calculations in simple systems
Reference values for deviation analysis

Formulas:

S = n C_V ln(T) + n R ln(V) + S_0
U = n C_V T (for monoatomic: C_V = 3R/2)
