An ideal gas held in a closed container undergoes a cyclic process A-to-B-to-C-to-A depicted in the pV diagram below. Determine the amount of heat added or removed from the gas. P (Pa)A C 8.0 x 103 1.0 x 103 B V (m') 2.2 x 10-2 12.4 x 10-2 Select one: O a. Q = 240 J O b. Q= - 470 J O c. Q = - 357 J ? O d. Q = 387 J
