Two 3.0 cm X 3.0 cm metal electrodes are spaced 1.0 mm apart and connected by wires to the terminals of a 9.0 V battery.

(a)What is the charge on each electrode? (pC)
(b)What is the potential difference between electrodes? (V)
(c)While the plates are still connected to the battery, inselated handles are used to pull them apart to a new spaceing of 2.0mm. What are the charge on each electrode? (pC)
(d) While the plates are still connected to the battery, inselated handles are used to pull them apart to a new spaceing of 2.0mm. What is the potential difference between electrodes? (V)

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
