(a) Final temperature
(b) Work done by the gas
(c) Heat input to the gas and
(d) The pressure ratio pmax/pmin

Question2
In a particular region of the earth's atmosphere, the electric field above the earth's surface has been measured to be 150 N/C downward at an altitude of 254 m and 165 N/C downward at an altitude of 399 m. Calculate the volume charge density of the atmosphere assuming it to be uniform between 254 and 399 m. Neglect the curvature of the earth.
