WebIn terms of physics, work is the transfer of energy from or to an object when it suffers a displacement due to the application of the force. Work has three main constituents: force , displacement and cause. WebWork done in this process is represented by the shaded area under the curve in figure (b). From figures (a) and (b) we can conclude that the work done is more when the system follows path ACB than the work done by the system along the path ADB. Thus, the work done by a system in a thermodynamic process depends not only on the initial and the ...
