Blowing out a Candle.....

A Candle is burning. You blow hard and the flame gets extinguished. Why??

What Do you think.....

It is because of the carbon dioxide we exhale when we blow out? No, this is not the reason. As a gust of wind can also blow out the candle and the wind carries a lot of oxygen along with it.

Let me tell you.....

Actually the reason is that when we blow hard we remove the warm air around the flame. Cooler air takes its place. This lowers the temperature of the burning wax to below its ignition point. The wax stops burning and the candle goes out.
