A gas ( γ = 1.4 ) of initial pressure p in a metal container is slowly compressed to one-third of its volume and then suddenly compressed to one-third of that volume. Find the final pressure in units

Question

A gas ( γ = 1.4 ) of initial pressure p in a metal container is slowly compressed to one-third of its volume and then suddenly compressed to one-third of that volume. Find the final pressure in units of p (two decimals).

TestHub · Accepted Answer

Metal walls make slow compression isothermal and sudden compression adiabatic. Slow: p → 3 p . Sudden: 3 p × 3 1.4 = 13.97 p . (Doing the sudden step first and the slow step second gives the same result.)
