Solution :`"State-1": """P= 1 atm""""V= 22.4L""""T= 273K"`
`"State-2": """P= 1 atm""""V= 44.8L""""T= 546K"`
`"State-3": """P= 0.5 atm""""V= 44.8L""""T= 273K"`
Step -A : Isobaricprocess
`W= - PDeltaV = - nRDeltaT=- R(273)`
`DeltaH=nC_(p,m)DELTAT = (5)/(2)Rxx 273`
`DeltaE=nCv_(m)DeltaT = (3)/(2)Rxx 273`
`q_(p) = DeltaH =(5)/(2)R xx 273`
Step -B : ISOCHORIC process
`W=0`
`DeltaH=nC_(p,m)DeltaT = -(5)/(2)Rxx 273`
`DeltaE=nC_(v,m)DeltaT = -(3)/(2)Rxx 273`
`q_(p) = DeltaE =-(3)/(2)R xx 273`
Step-C : Isothermal process
`W= - nRT ln.((V_(2))/(V_(1)))= 273ln2`
`DeltaH=0`
`DeltaE = 0`
`q= - W "" =- 273 R ln 2`
