摘要：

Specific heat capacities at a constant pressure of liquid ethanol in a temperature range from (265 to 348) K at a pressure of 500 kPa were measured by using flow calorimetry. The expanded uncertainty evaluated is from (0.55 to 0.89) % including the repeatability. Existing measurements by other researchers and derived specific heat capacity values from the existing equation of state provide greater values beyond the uncertainty. To confirm the reliability of our measurements, we measured the heat capacities under the same conditions for different liquid ethanol samples provided from different manufacturers. The measurements almost perfectly agree each other. The measurements obtained for two different samples of liquid ethanol are reported.
