← ScienceWhich mechanism increases overall entropy when frozen pipes burst?
A)Irreversible heat transfer✓
B)Adiabatic gas expansion
C)Reversible phase transition
D)Isothermal volume compression
💡 Explanation
Ice crystal expansion causes pipe rupture, thus irreversible heat transfer (thermodynamic non-equilibrium) occurs because heat dissipates into surroundings at varying temperatures. Therefore, entropy increases spontaneously, rather than due to adiabatic expansion under constant pressure, which returns to balance.
