Experimental Design for Specific Heat Capacity Testing

Specific heat capacity is fundamental to all types of transient and convection-based heat-transfer applications. Due to the relatively small magnitude of specific heat capacity effects, it has traditionally been a challenging property to measure accurately. Without careful consideration of effects like heat losses to the environment, heating rate, heat transfer within the instrument and the thermal inertia of the system itself, errors can be introduced to the measurement. Liquids and volatile samples especially require special attention due to the potential confounding effect of the heat of vaporization or sublimation of the sample. Selecting the wrong method for the application can result in significant errors in Cp characterization.

Dr. Reena Rahi joins us on October 17th to discuss these effects and how choose apparatus and design experiments to get an accurate and reproduceable specific heat capacity measurement.
