Sulfur Sublimation Experiment: Visual Guide & Science Demonstration #174950 (License: Personal Use)

This diagram illustrates the classic sulfur sublimation experiment, where a small piece of elemental sulfur is gently heated in a metal spoon using a candle flame. As the sulfur reaches ~115°C, it melts into a yellow liquid; above ~445°C, it vaporizes into a violet gas that re-condenses as crystalline deposits on cooler surfaces like the nearby dish. The setup highlights reversible phase transitions without combustion.

Used in middle/high school chemistry curricula and science outreach to demonstrate sublimation, phase changes, and safe handling of low-hazard chemicals; matches user intent for visual learning aids, lab procedure guides, or STEM education resources.
