Mechanical work vs thermodynamic work
WebThe first law of thermodynamics applies the conservation of energy principle to systems where heat transfer and doing work are the methods of transferring energy into and out of the system. The first law of … WebJun 13, 2024 · Figure 7. Reversible versus irreversible expansion of an ideal gas. In contrast, an irreversible expansion corresponds to movement of the piston when Pgas > Papplied, or equivalently, − Pgas < − Papplied. Therefore, the work done on the gas is less in the reversible case than it is in the irreversible case. (Both work terms are less than zero.

WebThe meaning of mechanical work is somewhat intuitive; it is energy spent in applying a mechanical force to produce a displacement- a change in size of a system. However, work can be described in more general terms and is comprised of many other forms in addition to mechanical work. WebIn physics, the term work has a very specific definition. Work is application of force, f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is …
