2. Setting Up the Work Equation: - The infinitesimal work done (dW) during an expansion against an external pressure (P) can be expressed as: dW=−PdV - The negative sign indicates that work is done by the system (the gas) on the surroundings. 3. Using the Ideal Gas Law: - Accord...
For the last part we have that so work done there is 0. To be able to reach the initial state again, there must be one step where the energy difference of the gas is positive and one step where it is negative. Your equation treats both steps like energy losses (work done by the ...
This creates a contradiction with the total entropy conservation expressed in equation (2). Discussion In summary, in this paper, we presented a framework for extending thermodynamics to individual quantum systems. Within this framework, we proved that the second law of thermodynamics holds and gave...

Equation (2.10) shows the work of adhesion for a liquid–solid combination. This definition is attributed to the French scientist A. Dupre. (2.10)Wa=γL+γS−γSL γL is the surface energy (tension) of the liquid phase, γS is the surface energy of the solid phase, γSL is the ...
(2) Work in thermodynamics is a generalization of the concept of work in mechanics as expressed in differential form in equation (2). The generalized coordinates in thermodynamics are the external parameters of a thermodynamic system. Examples are the system’s position in space and volume and th...
= force ds = displacement so if we apply force and it results in some displacement, then work is done by the force. so can we say that you have done some work while pushing a wall? let’s see, using the above equation, you have certainly applied some force, but since the ...
In thermodynamics, adiabatic processes are those where no heat exchange takes place between the work substance and the environment. Adiabatic processes can be classified in: {eq}\bullet {/eq} Reversible, satisfying the polytropic equation, {eq}pV^\gamma=C {/eq}, where {eq}\gamma=c_p/c_v...
