Question

Why does a candle stop burning when covered with a glass tumbler

Answer 1

The most essential component for combustion is oxygen. when we cover the candle with a glass tumbler the oxygen required for combustion reduces.thus the candle stops burning.

Answer 2

Answer:

• A candle will stop burning when covered with a glass tumbler because burning or combustion requires oxygen.
• Covering with a glass tumbler will limit the amount of oxygen inside the tumbler that is left for the candle to burn.
• Once all the oxygen is used up by the candle, it will stop burning.
• The carbon in the wax reacts with oxygen during the combustion reaction and produces carbon dioxide and heat.
• The carbon dioxide released will be left inside the tumbler that in turn will extinguish the fire or flame of the candle.
