Boiling by Cooling - Counter Example
Cooling the liquid does not cause the water to boil.
gases
Rising balloons
Balloons filled with gases less dense than air will rise.
Falling balloons
Balloons filled with gases more dense than air will fall.
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.
