Question 6.
Why does a burning candle go out when you blow on it?
Answer:
A burning candle goes out when you blow on it because when we blow air, we remove the hot air around the flame bringing down its temperature below the flash point.
Question 7.
Spraying water is not a good way of putting out an oil fire or an electrical fire. Why not?
Answer:
Spraying water is not a good way of putting out an oil fire or an electric fire. This is because, if water is sprayed on an oil fire, oil will come on the top layer of water and will still burn. As water flows quickly, it can take oil with it and thus increase the area where the fire can spread.
If water is sprayed on an electric fire, the person might get an electric shock and get killed.
Question 8.

Answer:
In order to prevent a fire at home and in the school, the following things can be done:

Turn off the gas supply of the stove after use.
(Students can add more points to this list by thinking about what measures can be taken to prevent fire at home and in the school)
