    Are Equations allowed in a Physics ESSAY?

    Say I'm asked to write a 1-2 page essay on Nanotech. Will adding equations improve my chances of better marks or cripple it?

    How Does Surface Tension Affect Thermodynamic Potentials in Soap Bubbles?

    For a system modelling a soap bubble, the differential work done is now given by: dW = −pdV + γdA, where γ is the surface tension and A the area. Compute new differential expressions for the potentials U, H, F, G. What are the new natural variables in each case? Are there any new Maxwell...

    Thermodynamics (Closed System) questions

    If I have a closed system where mass is conserved, what constraint will this bring on the system in terms of infinitesimal quantities. What conclusions can I then draw about the phases at this kind of equilibrium? Suppose we had an isovolumic, isothermal change, how would I have to alter my...
