Demonstration: This shows dramatic differences in the density of air, water and mercury.
Demonstration: An approach to the question: Does air have mass?
Class practical: This is a very quick experiment that provides evidence that air has mass. This still surprises some students!
Demonstration: This rough method can produce a difference of mass of at least 8 g . With enough apparatus it could be done as...
Demonstration: This simple experiment gives a reasonable value for the density of air.
Demonstration: This introduces the barometer tube and the pressure exerted by the Earth’s atmosphere.
Demonstration: Setting up a mercury barometer.
Demonstration: A mercury column supported by atmospheric pressure.
Demonstration: Pumping air from one side of a manometer.
Demonstration: Crushing an evacuated can.
Demonstration: This demonstration allows students to see air being removed by a pump.
