What I do

  • Apply the four laws of thermodynamics
  • Calculate heat transfer and work processes
  • Analyze thermodynamic cycles (Carnot, Rankine, refrigeration)
  • Model heat engines and refrigerators
  • Study phase equilibria and chemical potential
  • Apply Maxwell relations and thermodynamic identities

When to use me

When analyzing energy systems, designing heat engines, or studying thermal processes.

Key Concepts

  • First Law: ΔU = Q - W, energy conservation
  • Second Law: ΔS ≥ 0, entropy never decreases in isolated systems
  • Carnot Efficiency: η = 1 - T_c/T_h for heat engines
  • Clausius Inequality: ∮δQ/T ≤ 0 for cyclic processes
  • Gibbs Free Energy: G = H - TS determines spontaneity at constant T,P
  • Maxwell Relations: (∂S/∂V)_T = (∂P/∂T)_V connect thermodynamic variables
