This experiment compares the intermolecular forces of different liquids through a series of tests. Water is found to have stronger hydrogen bonding than ethanol or kerosene based on how they react to charged objects and spread on surfaces. A blade floats on water but sinks faster in kerosene due to hydrogen bonding supporting the blade. Adding detergent slows the blade's sinking by affecting water's intermolecular forces and viscosity. Ice is less dense than water, causing it to float. The volume of water does not change when ice melts back into liquid form. Intermolecular forces also influence properties like boiling points, with stronger forces requiring more energy to overcome attractions between molecules.
