then, simulations of an irreversible ideal gas process are presented using mathematica?, which we believe to be of pedagogical value in emphasizing the exposed ideas and clarifying some possible misunderstandings relating to the difficult concept of entropy [4]....
Similarly, using the appropriate equations for the partial specific internal energy u^i, enthalpy h^i, and entropy s^i, we can show that, for a mixture of ideal gases with constant specific heats, the partial specific properties of gas i in the mixture are the same as the corresponding ...
Here, \({{{\mathcal{R}}}\) is the universal gas constant, \({{{\mathcal{T}}}\) is the temperature, α0 is the ratio between the free solvent molar fraction in the solvated and unsolvated states, αi is the ratio between the molar fraction of unbound ions i = +, − ...
Now, a final thing to notice is that, positive or negative, the enthalpy of mixing absolute value is always rather small, below 1 kJ/mol. This should agree with practical experience: when you mix water and alcohol together, rarely do you feel them heat up (or cool down). So while thes...
Entropy change of air is determined considering variation of specific heats with temperature. The only relation we have for the entropy change of an ideal gas under variable specific heat assumption is Equation (8): 𝑠2−𝑠1=𝑠∘2−𝑠∘1−𝑅ln𝑃2𝑃1s2−s1=s2°−s1...
There are three numerical characteristics that characterize the random phenomenon in terms of an NC: 𝐸𝑥 (expectation), 𝐸𝑛 (entropy) and 𝐻𝑒 (hyper entropy). 𝐸𝑥 is the expected value of the sample data; 𝐸𝑛 is the spread of the sample values defining the uncertainty ...
