Falling balloons
Balloons filled with gases more dense than air will fall.
gases
Fluidity of carbon dioxide gas
Carbon dioxide gas is poured down a covered trough with candles inside.
Fluidity of methane gas
Methane gas from a beaker flows up a covered trough to a candle flame.
Atmospheric pressure
Atmospheric pressure causes the collapse of a metal can.
Effect of temperature on the volume of gas
Condensation of water vapor reduces the pressure inside a syringe.
Effect of condensation to liquid on the volume of gas
Condensation of water vapor causes atmospheric pressure to crush a can.
Effusion of gases introduction
The gas effusion apparatus is introduced.
Effusion of helium
Helium gas effuses through a porous cup, demonstrating the effect of the size and mass of molecules.
Effusion of methane
Methane gas effuses through a porous cup, demonstrating the effect of the size and mass of molecules.
Effusion of nitrogen
Nitrogen gas effuses through a porous cup, demonstrating the effect of the size and mass of molecules.
