A quantity of ideal gas is taken from state E to state F along the curvilinear path shown by the following data table, which lists five intermediate points that lie on the path.
Volume (L) 1.0 2.0 3.0 4.0 5.0
Pressure (kPa) 350 300 240 190 160
Between listed points, pressure varies smoothly with volume.
While the gas moves from E to F, 600 J of energy is transferred to it by heating.
(a) Using the tabulated data, estimate the work done BY the gas during the process E → F. Use an appropriate numerical method based on the information provided and clearly show your procedure.
(b) Determine the change in internal energy of the gas for the process E → F.
(c) State whether the temperature of the gas at F is higher, lower, or the same as at E, and justify your conclusion using your result from part (b).
