Thermodynamic Processes

A balloon filled with helium (32oC and 1.7 atm.) bursts. Immediately afterwards the expansion of helium can be considered as

Show answer and solution

Answer: (a)

  1. The burst is sudden, so there is no time for heat exchange: adiabatic.
  2. The gas expands rapidly and uncontrollably into the air, not through equilibrium states: irreversible.
  3. So the answer is (a) Irreversible adiabatic.
