- Consider 4.00 mol of an ideal gas with a constant‑volume molar specific heat of 12.5 J/(mol·K), an initial temperature of 26.8 ∘C, and an initial pressure of 5.710×104 Pa. The state of the gas is then changed to a final temperature of 48.1 ∘C and a final pressure of 3.090×104 Pa. What is the change in the entropy Δ? of the gas during this process? The gas constant is 8.31 J/(mol·K).arrow_forwardSome gas was compressed isothermally. This process was accompanied by a decrease in entropy (S=10 JK-1). Calculated the volume of the gas if it initially occupied the volume of 15.0 dm3 at 1.00 atm and 250 K. Does this violate the 2nd law of the thermodynamics stating that “the entropy of the isolated system can not decrease” ? Explain why.arrow_forwardThe entropy of a reversible process is Tds = du + pdv Obtain an expression for the change of entropy as a function of cp, P and T.arrow_forward

You can calculate the number of microstates (left/right distribution of molecules) possible by the equation W = N! / ( nL! * nR!,) where N is the total number of molecules and nL is the number on the left and nR is the number on the right. What is the entropy of the most disorganized distribution of gas molecules?arrow_forward
