Physics

3.19 A gas with adiabatic exponent γ is compressed adiabaticallyfrom an initial state (Pi, Vi) to final state (Pf, Vf). (a) Showthat the work done in this process is

W=((ViPi)/y-1)*[(Vi/Vf)^(y-1) -1]

(b) Evaluate the result numerically for one mole of helium gasinitially
at P = 1.0 atm and T = 300 K compressed to half its initialvolume.
(c) Compute the work done in an isothermal compression from thesame
initial point to half the initial volume. Explain the differencebetween
the numerical results for work done in adiabatic andisothermal
compression.
