Thermodynamics Fundamentals for Engineering Entrance Exams

Succeeding in competitive engineering entrance exams requires a rock-solid grasp of thermodynamic principles and the ability to apply them systematically to complex problems. This course breaks down challenging physical chemistry concepts into clear, digestible written explanations, helping you build both conceptual clarity and problem-solving confidence. You will transition from memorizing formulas to truly understanding the underlying physical laws and molecular behaviors. What you will learn: Understand the zero, first, and second laws of thermodynamics and their physical significance; Calculate enthalpy, entropy, internal energy, and Gibbs free energy changes for various processes; Apply thermochemistry principles to determine reaction enthalpies and bond energies; Analyze state functions, path functions, reversible, and irreversible processes; Solve numerical problems systematically using modern sign conventions and standard units; Master chemical equilibrium criteria and phase transition thermodynamics. This course begins with foundational definitions of systems, surroundings, and state variables before advancing to energy conservation and chemical energetics. It is designed specifically for students preparing for engineering entrance exams who want to strengthen their core chemistry and physics concepts, with no advanced prerequisites required.
