WebOct 19, 2024 · 1. If a force moves in the same direction as the force itself, then it is doing (positive) work. So if a gas pushes a piston outwards, we say that the gas is doing work on the piston, and therefore on the surroundings. But, you say, the surroundings are exerting a force 'inwards' on the piston. When the piston moves outwards, the force exerted ... WebSep 11, 2015 · My guess is: work done by a system, is the thermodynamical force generated by the system multiplied by its conjugate variable on the surroundings. As in my example here: a gravitational forcefield is generated by the system on the surroundings, and the conjugate variable displacement on the surroundings is multiplied by it.

When the system does work on its surroundings, energy is lost, and E is negative. When the surroundings do work on the system, the internal energy of the system becomes larger, so E is positive.

WebThermodynamics is the study of systems involving energy in the form of heat and work. A good example of a thermodynamic system is gas confined by a piston in a cylinder. If the gas is heated, it will expand, doing work on the piston; this is one example of how a thermodynamic system can do work.
