Titel Intermolecular Forces and States of Matter - Interactive Lecture Demonstration
Beschreibung This interactive lecture demonstration has the following learning goals - Students will be able to: (a) Distinguish between kinetic energy (KE), potential energy (PE) and total energy; (b) Apply the terms low and high PE for objects attracted to each other; (c) Identify electrostatic interactions as the force affecting the PE of atoms and molecules; (d) apply the terms low and high PE for atoms attracted to each other, resulting in bonds with different bond enthalpies; (e) Describe, at the particle-level, what happens during a phase change; (f) Apply the terms KE and PE for states of matter; (g) Connect particle-level descriptions of matter, including different phases, with macroscopic observations/properties.
