Explanation / Answer

a) PV = nRT V = 0.360m3 R = 8.314J T =21.2 substitute the values to get solution b) Eint = 3/2nRT   sbstitute thevalues to get solution c) At constant pressure workdone is W = PV =P(VB -VA) d)PV = nRT here V = 1.000m3 P value can beobtained by solving the part a).     substitute the values to get solution e)Eint = 3/2nRT here substitute T valuefrom part d).   ( internal energy is not depend onvolume.) f) Eint = E2 - E1substitute to get solution. i) Q = W+Eint substitute theabove values to get solution. g) U-W = Eint-Q substitute theabove values to get solution
