摘要
High-resolution adiabatic scanning calorimetry has been used to study the specific heat capacity anomaly of the nitrobenzene-tetradecane mixture near its upper critical point. The analysis, which is based on a method that uses heat capacity and enthalpy data, yields a value of the critical amplitude ratio A (+)/A (-) which is consistent with the universal, accepted one. The critical amplitude of the correlation length was derived via two-scale factor universality. All this information is compared to that reported in previous studies for nitrobenzene-alkane mixtures.
