Thermodynamics is a basic course for engineering field and very important to understand the course as it is a prerequisite for many future courses. Thermodynamics is part of physics that involves work, heat and temperature that are related to energy, chemical reactions and physical properties of matter. Thermodynamics also deals in studying systems and how they change according to their environment such systems are turbines, engines, nozzles and reactions in closed and open reaction systems. Thermodynamics stresses on the changes that deal with the free energy which consist of entropy, internal energy and enthalpy.    These questions are set up from different chapters of Thermodynamics I course, hoping to provide you with a wider knowledge on how to answer complicated questions and get you prepared for your Thermodynamics exams and quizzes.
