Work Step by Step

Reversible: A box sliding on a frictionless plane. A weighted piston sliding downward frictionlessly and compressing a. gas Irreversible: A box sliding on a plane with friction, coming to rest. A process where energy is lost to friction is not reversible. A plucked string sending out sound waves in all directions, eventually dissipating its energy in the form of sound waves and heat and coming to rest. The vibrations that are set up in the air carry away sound and kinetic energy, and this dissipative process is not reversible.
