Plastic Sulfur - Part 2 of 5
Solid sulfur is placed in a beaker and then heated in a bunsen burner flame. As the solid is heated, it begins to melt and a reddish brown liquid forms.
Solid sulfur is placed in a beaker and then heated in a bunsen burner flame. As the solid is heated, it begins to melt and a reddish brown liquid forms.
As molten sulfur is heated to 180 degrees Celsius, the free-flowing liquid thickens and becomes very viscous.
When viscous molten sulfur is heated to 200 degrees Celsius, more S-S bonds break and the sample is able to flow.
The cooled sulfur has become a flexible plastic.
An ice cube made from normal water floats in a beaker of liquid water.
Carbon dioxide gas is poured down a covered trough with candles inside.
Methane gas from a beaker flows up a covered trough to a candle flame.
Condensation of water vapor reduces the pressure inside a syringe.
Condensation of water vapor causes atmospheric pressure to crush a can.
The gas effusion apparatus is introduced.
