1-One mole of ideal gas at 270C 1-One mole of ideal gas at 270C. is expanded isothermally from a volume of 2.28 L to 4.256 L.CalculateW,∆E,∆H,q. 2-Calculat worke when 16 g of O2 at 300K is compressed from 1 atm to 100 atm(assume the work was reversibly).

3-When gas at 298.12K ,3 atm is expanded adiabatically and reversibly from 1.43 L to 2.86 L.Assuming Cp=28.8 J K -1 mol-1 A-What is the final temperature,pressure of the gas B-Calculate W,∆E, ∆H,q. 4-Calculate Cv, Cp.Assume gas are ideal if a=44.23 J K -1 mol-, b=8.79×10-3 J K -1 mol-,C=-8.6×105 J K -1 mol-,γ=1.31 at 273K

5- when 1 mole of liquid benzen is heated until evaporation is reversibly at 80.20C.the vapor is expands a gainst external pressure1 atm.Calculate W,∆E, ∆H,q 6-If the work done when the gas pressure in the cylinder 299 J in the process moved the amount of heat of 70.3 J from the gas to the surroundings, What is the change in internal energy of the system?
