Internal pressure is a measure of how the internal energy changes with expansion or contraction of a system at constant temperature. It is an important tool for studying the intermolecular interactions in liquids and liquid mixtures. Therefore, estimation of internal pressure and its corresponding excess value is very important. In the present work, we have estimated the excess internal pressure of three binary liquid mixtures at two temperatures using different approaches, out of them one is based on mole fraction and other is on volume fraction and a comparative study has been made between them.
