Problem
A candle is lit in a dark room.
• The solid wax near the flame softens and forms a clear liquid.
• The liquid wax is drawn up the wick and produces a bright flame accompanied by a faint soot deposit on a nearby glass slide.
For each of the two observations, classify the change as physical or chemical and justify your choice with one brief piece of evidence.
