MCQ
If a cylinder containing a gas at high pressure explodes, the gas undergoes
  • A
    Reversible adiabatic change and fall of temperature
  • B
    Reversible adiabatic change and rise of temperature
  • ✓
    Irreversible adiabatic change and fall of temperature
  • D
    Irreversible adiabatic change and rise of temperature
✓

Answer

Correct option: C.
Irreversible adiabatic change and fall of temperature
Gas cylinder suddenly explodes is an irreversible adiabatic change and work done against expansion reduces the temperature.
