Question

For the thermodynamic processes in the figure below, what is the approximate value of the work done on the system? (use the exact values you enter in previous answer(s) to make later calculation(s).) Estimate the coordinates of l. (Assume V_1 = 0.33 m^3 and V_2 = 0.06 m^3.) V_i = m^3 P_i = Pa Estimate the coordinates of f. V_f = m^3 P_f = Pa Calculate the work done on the system.

Explanation / Answer

For the first figure

a) i: Vi = 0.02 m^3, Pi = 3.5 x1 0^5 Pa

f: Vf = 0.065 m^3 , pf 3.5 x 10^5 Pa

work done= P dv =3.5 x 10^3 ( 0.065 - 0.02)=157.5 J

b) i : Pi = 19500 Pa, Vi =0.09 m^3

f : Pf =10,000 Pa , vf = 0.2 m^3

work done= nRT ln ( V2/V1)

P1V1= nRT = 19500 ( 0.09) = 1755

W = 1755 ln ( 0.2/ 0.09)= 1401.381 J apprx

c)
