Abstract
This study aims to experimentally determine the role of intermolecular forces on the instability of absorption and release of heat in Kapok oil. Heat absorption and release were measured using a Differential Sanning Calorimeter (DSC). The thermogram shows that heat absorption and release are unstable. The results indicate that the during the first cooling process, there is a shoulder visible in the thermogram which is caused by a separation between the molecules in the Kapok oil. The longest molecule has the most energetic Van der Waals interaction. The Van der Waals interaction exists even when the vibration of the molecule becomes weak. Therefore, a long particle attracts another long particle and a short particle attracts another short particle. The separation causes the instability of heat absorption and release.
