Question

What are macroscopic forces exerted by system in thermodynamics?

Answer 1

In thermodynamics, work performed by a system is energy transferred by the system to its surroundings, due solely to macroscopic forces exerted by the system on its surroundings, where those forces, and their external effects, can be measured.The externally measured forces and external effects may be electromagnetic, gravitational, or pressure/volume or other macroscopically mechanical variables
