Computation of Isobaric Thermal Expansivity from Liquid Density Measurements. Application to Toluene

We discuss several methods for estimating isobaric thermal expansivity from liquid density measurements. A new numerical method was proposed for estimating the isobaric thermal expansivity and its uncertainty from a limited number of experimental density data. This new computation scheme based on the curve linearization method was used to determine the thermal expansivity of toluene from two literature density data sets.
