A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

This demo does not actually belong to SFU Physics. It is property of the Andreoiu Lab in Chemistry. We should give them at least a week of notice that we want to borrow it, and even then, we are not ...

Diffusion is the movement of particles from a region where they are in high concentration to a region where they are in low concentration, and is one of the ways substances can move across the ...

The cloud chamber detects secondary cosmic rays and radioactive decays by making alcohol clouds along the particle paths through the chamber. Particles ionize alcohol molecules as they pass through ...

Ms. Seale, High School Science teacher in Philadelphia, leads an at home science experiment showing the diffusion of molecules. Ms. Seale, High School Science teacher in Philadelphia, leads an at home ...

In this experiment, bovine serum albumin (BSA) will be used as the soluble antigen and anti-BSA antiserum as the antibody preparation. The Ouchterlony gel diffusion test is done in an agar gel ...

Particles in a liquid and a gas move continuously. Because of this movement, particles will spread themselves evenly throughout a liquid or a gas. Diffusion is an essential process in cells.
