That is, the value of s+ of an ideal at a given temperature can be determined by subtracting R lnT from the value of s° at the same temperature. Then, the entropy change of an ideal gas can also be expressed as 𝑠2−𝑠1=𝑠+2−𝑠+1+𝑅ln𝑣2𝑣1s2−s1=s2+−...
If we follow the change of the SMI we will observe a nearly monotonic increasing function of time. For actual simulations, see Ben-Naim (2008, 2010) [3,9]. The larger N, the more monotonic the curve will be and once n reaches the value: 𝑁/2N/2, the value of the SMI will ...

found, the total number of micro state control system of an ideal gas by volume, temperature of macroscopic parameters, then get the total entropy of the system is equal to the volume and temperature of entropy and entropy (see article), by examining the concept of entropy entropy change ...
Ice turning to gas is A) Endothermic B) Exothermic C) Decrease in entropy Predict the sign of the entropy change for the process: An ice cube is warmed to near its melting point. Consider the change in entropy that occurs when a liquid freezes and explain why t...
24-3 Entropy Change for Irreversible Processes How can we calculate the entropy change in an irreversible process? 1). Find a reversible process that connects these same two states. Any of the many such processes will do. 2).Calculate S for this chosen equivalent reversible process. The ...
So change in entropy of the surroundings from A to D is determined by its temperature and the heatflow from the system to the surroundings. A reversible path from A to D is an isothermal process in which total heat flow Q flows to the surroundings where Q is the mass of the water x ...
