Intermolecular Forces Activity

Introduction and Setup00:00:00

Overview of the lab materials, including acetone, water, ethanol, sodium chloride, mineral oil, and saline, and the experimental setup for testing solubility and evaporation.

Theoretical Background00:01:42

Explanation of the intermolecular forces (LDF, dipole-dipole, hydrogen bonding, and ionic) and polarities of the substances used in the experiment.

Solubility Testing00:04:41

A step-by-step demonstration of mixing the different liquids and solids to observe solubility, with visual analysis of the results using dark paper for contrast.

Evaporation and Heat Tests00:12:08

Testing the cooling effect of the substances on the skin to determine their evaporation rates, linking these observations back to intermolecular forces.
