At 1 atm, a liquid is heated above its normal boiling point. -ΔS_surr for this process is

Quizplus · Accepted Answer

When a liquid is heated above its normal boiling point, it undergoes a process called superheating, where the liquid exists in a metastable state. This means that the entropy of the system has increased, leading to a positive ΔS. Since the surroundings absorb heat during this process, the entropy of the surroundings decreases, leading to a negative ΔSsurr. Therefore, ΔS_surr = ΔSsurr - ΔS > 0 - ΔS = less than zero. Hence, the correct answer is A.
