The weaker intermolecular forces? For this lab, I predicted that vinegar would have stronger intermolecular forces and a higher boiling point compared to apple juice. This encompasses all of our higher education and high school simulations across various disciplines (including, but not limited to: Biology, Chemistry, Engineering, Medicine, General Science, and Physics). It is now your mission to put them back. Intermolecular forces, often abbreviated to IMF, are the attractive and repulsive forces that arise between the molecules of a substance. in this experiment.
