Enthalpy In A Box: Teaching Open Vs. Closed System Work Terms
... Enthalpy, somewhat like entropy appears to be one of thermodynamic’s mysterious and abstract properties due primarily to difficulty in physical comprehension. Unlike entropy however, one could argue that enthalpy does not bring as much to the table. After all, it is defined, somewhat arbitrarily, fr ...

Work, Energy and Momentum Notes
... Suppose you sit down on a 8.0 oC concrete bench. You are only wearing a thin layer of clothing that provides negligible insulation and therefore your core temperature (37 oC) is only protected by 1.2 cm thick layer of fat (on your bum!) that touches the bench. Let’s estimate the area of contact betw ...

To measure the smashing potential of this block, let’s determine the change in the block’s kinetic energy after the piston pushes it a distance d. The initial and final states of the process are pictured to the right. a) Draw a fo ...

The Thermodynamic Potentials
... Since, dA = - P dV for an isothermal process, we have: - P dV - P dV ≤ 0 If the volume changes of the subsystems occur according to the diagram above, then dV = + dV and dV = - dV. So: (P - P) dV ≤ 0 If the volumes change, then P > P. If the system is at equilibrium, then P = P. ...
