Liquefaction of Carbon Dioxide - Part 2 of 4
The liquefaction of carbon dioxide is shown. In Part 2, the valve is closed and the pressure in the tube builds until all three phases of carbon dioxide are present.
physical properties
Liquefaction of Carbon Dioxide - Part 3 of 4
The liquefaction of carbon dioxide is shown. In Part 3, the pressure in the tube continues to rise until the valve is opened, at which point the pressure drops and the liquid changes to solid.
Liquefaction of Carbon Dioxide - Part 4 of 4
The liquefaction of carbon dioxide is shown. In Part 4, an animation is used to illustrate the correlation between phase and pressure.
Viscosity of Liquids - Octane
The relative viscosity of octane can be measured using a stopwatch, and compared to other liquids.
