Familiarity with systems, properties, and thermodynamic states
A calculator and willingness to practice exam-style problems
Description
The First and Second Law of Thermodynamics form the core of most thermodynamics exams and they are where many students lose the most points.This course is designed to help you confidently apply the First and Second Law of Thermodynamics in exam problems involving heat, work, mass flow, and performance limits. Instead of focusing on abstract theory, the course takes an examdriven approach, showing you how these laws are actually used in typical engineering exam questions.You'll learn how to correctly set up mass and energy balances, identify heat and work interactions, apply consistent sign conventions, and analyze control volume problems involving flow and enthalpy. The course also introduces the Second Law in a practical way, helping you understand irreversibilities, performance limits, and how to calculate the coefficient of performance (COP) for refrigeration and heat pump systems.Throughout the course, the emphasis is on building a clear, repeatable problemsolving method. Each concept is connected directly to examstyle examples so you always understand how and when to apply it. Common exam mistakes are highlighted and addressed explicitly, helping you avoid losing points due to confusion or setup errors.This course is intended as a focused complement to your university thermodynamics lectures and works especially well if you already understand the basics but struggle to apply the First and Second Law under exam pressure.By the end of this course, you will be able to:Apply the First Law to mass and energy balance exam problemsCorrectly calculate heat and work in closed and open systemsAnalyze control volume problems involving mass flow and enthalpyApply the Second Law to evaluate irreversibilities and limitsCalculate and interpret COP in refrigeration exam problemsIf you want to move beyond memorizing formulas and instead develop a reliable method for solving thermodynamics exam problems, this course is built for you.
Who this course is for
Engineering students preparing for thermodynamics exams who want to confidently apply the First and Second Law
Students who understand basic thermodynamics concepts but struggle with heat, work, energy balances, and entropy in exam problems
Students who want a clear, exam-focused explanation of COP, irreversibilities, and performance limits
Anyone who wants a structured method for solving First and Second Law exam problems without unnecessary theory
