Question

A thermodynamic system is taken from state a to state c in the figure (Figure 1)along either path abc or path adc. Along path abc the work W done by the system is 450J. Along path adc, W is 120J. The internal energies of each of the four states shown in the figure are Ua=150J,Ub=240J,Uc=680J, and Ud=330J.

Answer 1

Answer:

A) 90

B)absorbs heat

C)890

D)absorbs heat

E)300

F)absorbs heat

G)350

h) absorbs heat

Explanation:

A)heat flow ab

240-150=90

C) heat flow bc

680-240=440

work done =450

440+450= 890

E) heat flow ad

330-150=180

work done= 120

180+120=300

G)heat flow dc

680-330=350
