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