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 ...

HDPCG consists of multiple trays that house vapor diffusion and liquid liquid diffusion experiments inside a MERLIN unit which can be preconditioned to a wide range of set points. With our hardware ...

A presenter-led live action video showing a science experiment about how to investigate osmosis, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge. Osmosis is the diffusion of water molecules ...

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 ...
