Second Law of Thermodynamics and Heat Engines
The rule that gives natural processes a direction, and how engines convert heat into work.
Second Law of Thermodynamics
Heat cannot spontaneously flow from a colder body to a hotter one without external work being done — natural processes have a preferred direction.
Heat Engines
A heat engine converts heat energy into mechanical work, operating between a hot and a cold reservoir. No heat engine can be 100% efficient.
Reversible and Irreversible Processes
A reversible process can be reversed without leaving any change in the surroundings; most real-world processes are irreversible.
