Isothermal processes

[105561735]

Just out of curiosity which natural or man-made processes are isothermal in nature

[Anya 1G]

One example is some heat engines, such as certain types of gas turbines, which use isothermal expansion to convert heat energy into mechanical work while maintaining constant temperature. Another example is refrigeration systems, where gases are compressed isothermally to maintain a constant temperature during compression, which helps in cooling processes in an efficient manner.
