Kinetic and Diffusive Processes


I6-37: MOLECULAR MOTION DEMO - VAN DER WALLS FORCES

Purpose: Introduce the concept of attractive force between molecules.

I6-36: MOLECULAR MOTION DEMO - AVOGADRO'S HYPOTHESIS

Purpose: Help justify Avogadro's hypothesis using a model.

I6-25: DIFFUSION - DISTRIBUTION OF PING PONG BALLS

Purpose: Demonstrate on a macroscopic scale using ping pong balls how random molecular motion causes substances to diffuse.

I6-24: DIFFUSION VELOCITY

Purpose: Show that the diffusion velocity is proportional to the RMS molecular velocity.

I6-11: BROWNIAN MOTION WITH TV

Purpose: Demonstrate Brownian motion.

I6-02: NITROGEN DIAMETER AND MEAN FREE PATH
