Question

what happens when roll sulphur is heated to it's boiling point and then cooled in cold water? ​

Answer 1

Sulphur starts to melt at 115 degrees Celsius. At 200 degrees Celsius, there is a colour change from yellow to red and starts to boil at 400 degrees Celsius. Before reaching the boiling point, it starts to vaporize. When it is heated above 445 degree Celsius, it will ignite.
