The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.

The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic processes: The first law makes use of the key concepts of internal energy, heat, and system work. ... It is just that W is defined as the work done on the system instead of work done by the system.

The second law of thermodynamics states that the total entropy of an isolated system always increases over time, or remains constant in ideal cases where the system is in a steady state or undergoing a reversible process.

Image result for Carnot Engine
A Carnot heat engine is an engine that operates on the reversible Carnot cycle. The basic model for this engine was developed by Nicolas Léonard Sadi Carnot in 1824.

Thermodynamics.

The eldest son of Lazare Carnot, Sadi

was born in the Palais du Petit-Luxembourg, where his father lived as a member of the Directory. The powerful and often turbulent worlds of French politics and science were an integral part of the environment in which Sadi and his younger brother Hippolyte spent their youth. Withdrawing from public life in 1807, Lazare Carnot concentrated on science and the education of his sons. Through his studies Sadi acquired not only his taste and aptitude for mathematics but also a solid training in physics, the natural sciences, languages, and music.
