6. Why does a burning candle go out when you blow on it?

Ans: When we blow on candle, the hot air around the candle gets removed and it brings down the temperature of candle below the flash point. Thus, a candle goes out because no fuel can burn below its flash point.

7. Spraying water is not a good way of putting out an oil fire or an electrical fire. Why not?

Ans: Spraying water is not a good way of putting out an oil fire or an electrical fire. If water is sprayed onto an oil fire, the oil will float to the top of the water and continue to burn.
