Answer #1

+Since - according to Charles-Gaulussac's law

T2 / T1 = V2 / V1

Where, T1 = 15.9+273 = 288.9 K

              T2 = 87+273 = 360 K

and we can use the following formula to calculate the entropy change,

Since - DS = DH / T = [nRT ln (V2/V1) ] / T = nR ln (V2/V1)

Thus - DS = (3.4)(8.314) ln (360/288.9)

                 = = - 6.219 J/K

The working substance of an engine is 1.00 mol of a monatomic ideal gas. The cycle begins at P1=1.00 atm and V1=24.6L. The gas is heated at constant volume to P2=2.00atm. It then expands at constant pressure until its volume is 49.2L. The gas is then cooled at constant volume until its pressure is again 1.00 atm. It is then compressed at constant pressure to its original state. All the steps are quasi-static and reversible. Calculate the TOTAL work done...
