pi vi^1.4 = pf vf^1.4 where i is initial and f is final
so
vf^1.4 = pi/pf vi^1.4 = 140/700 (.2)^1.4 = 0.2 * 0.105
vf^1.4 = 0.0210
1.4 log vf = log 0.0210 = -1.678
log vf = -1.198
vf = 0.0633 m^3
so
vf^1.4 = pi/pf vi^1.4 = 140/700 (.2)^1.4 = 0.2 * 0.105
vf^1.4 = 0.0210
1.4 log vf = log 0.0210 = -1.678
log vf = -1.198
vf = 0.0633 m^3
