Outline the procedures used to calculate the motion of molecules in fluids and atoms in molecules.
Homework Answers
The random motion of particles in a fluid (liquid or gas) is
called brownian movement.
where D is the diffusivity (m2 ˣ s-1 ), R is the gas constant (J ˣ mol-1 ˣ K-1; kg ˣ m2 ˣ s-2 ˣ K-1 ˣ mol-1), T is the temperature (K), N is the Avogadro constant, η is the dynamic viscosity (Pa ˣ s; kg ˣ m-1 ˣ s-1), r is the averaged particle radius (m), and t is the time passed (s).

Static Fluids/Fluids in Motion A 2 cm diameter hose has water flowing through it at a speed of 1.5 m/s before reaching a nozzle that sends water out at 18 m/s. What is the diameter of the nozzle? If the water leaving the hose is used to fill up a barrel, how many liters of water are in the bucket after 3.5 minutes

Atoms and Molecules can't really be "seen" in real time. They are too small, and we don't currently have the technology to image at that scale in full motion. Accordingly, atoms and molecules tend to get classified as abstract points, and not real particles that have a distinct shape. Reflect on VSEPR (Valence shell electron-pair repulsion) theory and molecular shape; in that context, did you classify atoms and molecules as abstract or real? Do you think you have a good...
