Agas contained in a piston–cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 1 bar, v1 = 1 m3, u1 = 400 kj and p2 = 6 bar, v2 = 0.167 m3, u2 = 420 kj: process a: constant-volume process from state 1 to a pressure of 6 bar, followed by a constant-pressure process to state 2. process b: process from 1 to 2 during which the pressure volume relation is pv = constant. kinetic and potential effects can be ignored. for each of the processes a and b, (a) evaluate the work, in kj, and (b) evaluate the heat transfer, in kj.

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
