A “Sorbet state” (at a moderate temperature below 0°C) can be regarded as {a mixture of [ice (water solid) with a higher melting point] and [a water solution (containing sugar and fruit juice) with a lower liquidus temperature]}.
所谓的雪糕状态,是指平均温度在0摄氏度以下的一种冰水混合物。冰是指水的固相形态,且具备稍高的熔点,而水是指包含果汁和糖分在内的一种液相形态,具备稍低的液相线温度。
[This drop of liquidus temperature (melting point)] is a result of [a drop in the chemical potential of the solution], [which keeps an equilibrium with the solid-state solvent], explained by well-known thermodynamics as “freezing point depression”.
根据众所周知的热力学经典——凝固点降低理论,这种相对较低的液相线温度(熔点),其实是由于溶液中可以保持固态溶剂平衡的化学势降低所致。 |
