Solving First Law of Thermodynamics Problems

Struggling to apply thermodynamic formulas to actual exam and engineering problems? Understanding the theory is only half the battle; the real challenge lies in translating word problems into correct mathematical equations. This course bridges the gap between thermodynamic theory and practical problem-solving. You will start by mastering foundational definitions of systems, boundaries, state variables, and sign conventions before moving on to structured, step-by-step calculations. Through clear, written explanations and structured practice scenarios, you will develop the analytical skills needed to approach any energy balance problem with confidence. What you'll learn: Understand foundational concepts of open, closed, and isolated systems; Apply the sign conventions for heat transfer and work done by or on a system; Solve closed-system energy balance equations for various thermodynamic processes; Calculate enthalpy, internal energy, and boundary work using thermodynamic tables; Analyze open-system steady-flow devices like nozzles, turbines, and compressors; Practice modern systematic problem-solving workflows to avoid common algebraic errors. The course begins with essential terminology and governing equations, then guides you through progressively complex scenarios, from basic closed systems to steady-flow engineering devices. This course is designed for engineering students, physics enthusiasts, and beginners looking for a structured, text-based guide to mastering thermodynamic calculations with no advanced prerequisites.
