Explanation / Answer

Given that,

m = 9 g

so, number of moles n = 9 / 4 = 2.25

P = 2*101325 = 202650 N/m^2

T1 = 37 + 273.15 = 310.15 k

(A)

From ideal gas equation,

PV = nRT

V1 = 2.25*8.314*310.15 / 202650

V1 = 0.0286 m^3

(B)

T2 = T3 (isothermal)

T3 = 657 + 273.15 = 930.15 k

V3 = nRT3 / P

V3 = 2.25*8.314*930.15 / 202650

V3 = 0.0858 m^3

(C)

P2 = nRT2 / V1

P2 = 2.25*8.314*930.15 / 0.0286

P2 = 608386.39 N/m^2

P2 = 6 atm

(D)

From the figure,

T2 = T3 (isothermal)

T3 = 657 oC
