1 mol of an ideal gas is transformed from an initial state Ti= 320 K and Vi = 80.0 L to a final state characterized by Tf = 650 K and Vf = 120 L. Calculate delta S for this process. Please show all work! thanks!
Physical Chemistry Calculate the change in entropy when one mole of metallic aluminum is heated at one bar pressure from an initial temperature of 25 °C to a final temperature of 750 °C. The molar heat capacities of solid and liquid aluminum at one bar pressure are 29.2 J mol K1 and 31.75 J mol K, respectively. The specific enthalpy of fusion of aluminum at its melting point (660.46 °C) is 396.57 J g1. The molar mass of aluminum is...

Expand 1.00 mol of a monatomic gas, initially at 7.00 kPa and 737 K, from initial volume Vi = 0.875 m3 to final volume Vf = 2.90 m3. At any instant during the expansion, the pressure p and volume V of the gas are related by p = 7.00 exp[(Vi - V)/a], with p in kilopascals, Vi and V are in cubic meters, and a = 2.40 m3. What are the final (a) pressure and (b) temperature of the gas?...

8. Initially, 1 mole of the real gas is contained in a thermally insulated piston-cylinder arrangement in an initial state (T1, P1, Vi ). 1 mole of the real gas that is expressed by the following equation of state under the investigation. Now, the gas is expanded so as to fill the final state of (T2, P2, V2 ). Suppose that any possible temperature dependence of Cy is negligibly small and the molar heat capacity is approximately equal to 2"...
2. One mole of an ideal gas, CP - (7/2)R and CV - (5/2)R, is compressed adiabatically in a piston/cylinder device from 2 bar and 25°C to 7 bar. The process is irreversible and requires 35% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas?
One mole of an ideal gas from an initial state described by T= 250 Kand P= 1.00 bar with CV,m= (5/2)Rundergoes an adiabatic expansion against a constant external pressure of 0.500 bar until the final pressure is half its initial value. What is w, and ΔS for this process? Note that the process involves both changes in T and P.
