Explanation:
Beacause when you light the candle the candle wax melt and vaporize due to heat produced by the flame and this wax vapour give new substance like CO2 carbon soot so it is chemical change.
Because when electric current pass through a filament of bulb the filament star glowing and the glow stop as current off.
In this Chemical compostion of tungsten of filament dose not change so this is physical change.
Thank you.
