how will you show that air is needed for burning
Answers
Answer:
Explanation:
Fire is a chemical reaction that creates light and heat from oxygen and fuel. A lit candle needs to draw oxygen from the air in order to continue burning. If you limit the amount of air available, the candle's flame eventually goes out once it uses up all the oxygen
Answer:
we can prove it by doing an activity
activity:
take a candle and fixed on a table..The candle is lighted...the candle will continue to burn due to continously available fresh air providing the required oxygen for combustion....
Now cover the burning candle by putting an inverted gas jar over it..after a short time the candle stops burning and and gets extinguished...
this proves that air is necessary for combustion of substances....
hope it helps you....have a great day...
