A object having Black red and gray colour riddle
Expert Asked on 26th June 2016 in Easy puzzles.
The answer to this riddle is “charcoal.”
When charcoal is bought, it is black in color, as it is made from carbon-rich materials like wood or coconut shells that are heated in the absence of air.
When charcoal is used, it turns red when it is lit and burns.
When charcoal has been used up, it turns into gray ash, which is what is left when the carbon in the charcoal has been fully burned away. This gray ash can then be thrown away.
