Hello Mechanical engineering students,

Thermodynamics is the study of the relationship between heat, work, and energy. The course provides students with an understanding of the fundamental principles of thermodynamics and their practical applications. The course covers topics such as the properties of pure substances, the first and second laws of thermodynamics, entropy, and thermodynamic cycles. Students will learn about various thermodynamic processes, including isothermal, adiabatic, and polytropic processes, and their applications in engineering. The subject also emphasizes the importance of conservation of energy and its application to real-world problems. By studying thermodynamics, students can gain a better understanding of how energy works in systems and how it can be utilized in various applications, such as power generation and refrigeration.
