The experiments in this section provide opportunities to extend knowledge and understanding of states of matter, changes of state and collision theory.
While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.
We are starting with GCSE-level experiments.
Experiments
-
Detergents, soaps and surface tension
Adding detergents and soaps to powders floating on water, or to a floating needle, illustrates their effect on surface tension.
-
Supercooling - the energetics of freezing
This experiment demonstrates the phenomenon of supercooling and illustrates the various associated energy changes which occur.
-
Determining the relative molecular mass of butane
A simple, quick and direct method for finding relative molecular masses (RMM) of gases, such as butane, that are available in small pressurised cylinders.
-
A solid-solid reaction
Solid lead nitrate and solid potassium iodide are shaken together in a small jar. They quickly react to make yellow lead iodide.
-
Diffusion of gases – ammonia and hydrogen chloride
A demonstration to show the diffusion of gases.
-
Liquefying chlorine gas
This experiment shows how easy it is to liquefy chlorine gas by cooling alone.
