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.

A cast iron bomb is completely filled with ice water, then placed into a dry-ice/acetone slush and covered with a wooden box. When the water in the bomb freezes, the cast iron bomb explodes, breaking into several pieces, and destroying the box in which it was placed.
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.
