1st. Principle-- If two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other.
2nd. Principle-- Heat energy and mechanical work are mutually convertible.
3rd.-- It is impossible to construct a mechanical device ( engine) whose sole purpose is to convert all of the heat energy supply to it into equal amount of work.
4th.-- The entropy of a pure crystalline substance at absolute zero temperature is zero
The study of converting heat into mechanical energy is called thermodynamics. It is a branch of physics that deals with the relationships between heat, work, and energy. Thermodynamics is essential for understanding and optimizing processes such as engines, refrigeration, and power generation.
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
Two scientists who are generally thought of as establishing the laws of thermodynamics are French physicist Nicolas Léonard Sadi Carnot who studied the efficiency of heat engines believing it was the key that could help France win the Napoleonic Wars and Scottish physicist Lord Kelvin who was was the first to formulate a concise definition of thermodynamics in 1854.
The study of heat is called thermodynamics.

The study of heat energy and its transformation is called thermodynamics. It involves the relationship between heat, work, and energy, and how they are transferred or converted in various systems. Thermodynamics is essential in understanding processes such as heat engines, refrigeration, and chemical reactions.

The branch of physics that deals with heat energy is called thermodynamics. It studies the relationships between heat, work, and energy transfer in systems. Thermodynamics is essential for understanding processes like refrigeration, engines, and phase transitions.
Thermal is an adjective, meaning to do with heat. Thermodynamics is a noun, a branch of physics to do with the thermal properties of materials, and has several laws which are the basis of design of heat engines and other thermal processes.
The statement that there can be no perfect heat engines is declared by the Second Law of Thermodynamics. This law states that it is impossible for any heat engine to have 100% efficiency in converting heat into work.
The Clausius inequality is important in thermodynamics because it helps us understand the direction in which heat flows in a system. It states that heat naturally flows from hot to cold regions, and helps us predict the efficiency of heat engines.

Heat is a concept studied in the branch of physics known as thermodynamics. Thermodynamics deals with the relationships between heat, work, energy, and temperature.
thermodynamics, is essential for mechanical engineers, because the subject is mainly about heat and work in system, and as an engineer that is important, especially when you have to design engines, because that is when you have to determine important factors such as the amount of work that can be done by that engine internally, and the heat it transefered and obtained.
