Surface Pressure Dependence of A-T Isobars and Two-Dimensional Thermal Expansion coefficient of Insoluble Monolayers of Tristearin at the Air/Water Interface
Pressure dependence of A-T isobars of insoluble monolayers of tristearin(TS) was measured with the instrument developed in our laboratory. The isobars look like a group of straight lines in the temperature span measured (5–45 °C). Pressure dependence of the two-dimensional thermal expansion coefficient of the monolayers was calculated by the numerical differentiation of the A-T isobar data with respect to temperature using a simple regression analysis.
