Chemistry experiment - Heating Sulfur (8 parts) 1) Powdered rhombic sulfur is heated and begins to melt. 2) The sulfur becomes completely molten at 112.8 C . 3) The color of the liquid sulfur deepens as the temperature rises. 4) The liquid reaches its maximum viscosity at 190 C: it will hardly pour. 5)the very dark liquid becomes mobile again above 190 C. 6) The hot liquid is quickly poured into cold water. 7) The sulfur that has suddenly solidified does not resemble the original rhombic form. It has an amorphous structure and is know as plastic sulfur. 8) Plastic sulfur is dark and elastic.
