The molar internal energy and enthalpy of mixing equals the corresponding excess property, since they do not include an entropy contribution. In order to account for different molecular sizes, the molar combinatory (C) Gibbs (free) energy of mixing is represented by combinatory entropy of mixing ...
It says that the energy fluctuation in an open system equals that in the equivalent isothermal system plus a term proportional to the fluctuation in particle number. The proportionality constant is the square of the rate of change of the equilibrium energy with particle number. Equivalent here ...
Pretty much everyone, including the innumerate, has heard of Einstein’s E = mc2, energy equals mass times the speed of light squared.PBS calls itthe world’s most famous equation. While it is profound to prove that energy and matter are interchangeable, in day-to-day terms it’s not th...
So, one pound-force equals 32.174049 lb-ft/s². In the next section, we shall attempt to show you how to handle unit conversions when you're calculating bullet kinetic energy. How to calculate bullet energy in ft-lbs Say you have bullet mass in grains and velocity in foot per second....
1 concept Energy in Pendulums Video duration: 6m 3 Problem A mass swinging at the end of a pendulum has a speed of 1.32m/s at the bottom of its swing. At the top of its swing, it makes a 9° with the vertical. What is the length of the pendulum?
If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem). We will find it more useful to consider just the conversion of PEg to KE without explicitly considering the ...
Force is mass times acceleration: F=ma. If you apply a force over atimeyou get momentum and if you apply force over adistanceyou get energy. Acceleration times time is velocity, so it should more-or-less make sense that force times time is momentum: ...

Numerical simulation was performed using a commercial finite-element software package COMSOL (version 4.3) Multiphysics. The Poisson–Nernst–Planck (PNP) equations which were employed to quantitively describe the ionic mass transport process as depicted below: ...
