Why can you hold your fingers beside the candle flame without being harmful but not above the flame?
Beside the flame the heat you experience is that heat being radiated as light - if you hold your finger too close or leave it too long, you will get harmed! Beside the flame the air is cool as cool air is being sucked into the flame. However above the flame the hot gases produced by the combustion of the wax in the flame are rising upward by convection. These hot gasses will heat you skin by conduction and you will be burned very quickly.
Why does the flame of a candle die when you cut off air supply?
The flame of a candle requires oxygen to continue burning. When you cut off the air supply, the flame is deprived of oxygen which is essential for the combustion process. Without oxygen, the flame cannot sustain itself and eventually dies out.
When air hole of the Bunsen burner is closed what is the observation?
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
What happened to the flame as you covered the air holes?
The flame will start to weaken and eventually go out as you cover the air holes. This is because the flame needs oxygen to sustain combustion, and by covering the air holes, you are restricting the flow of air needed for the flame to burn.
What flame is what you called when air holes are closed?
Safety flame
How long can you last without air?
'Bout 4 minutes

How did the safety flame on a Bunsen burner get its name?
The safety flame on a Bunsen burner got its name from its primary function of preventing accidents and ensuring safety in the laboratory setting. When the air hole on the Bunsen burner is closed, the flame produces a yellow, sooty flame that is not as hot or as safe for heating purposes. By adjusting the air hole to allow for proper air flow, the flame turns blue and produces a hotter, cleaner flame, hence the term "safety flame."
Why does camel last long than humans without water?
They can last longer because they are said to have areas in their body (humps) that can adsorb the water in the air (humidity).

When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
Why does a hot air balloon need flame in order to take off?
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
What do you do to a Bunsen burner to create a safety flame?
To create a safety flame on a Bunsen burner, adjust the air hole to allow more air to mix with the gas. This will produce a hotter, lighter blue flame rather than a yellow, sooty flame. Adjust the gas flow until the flame burns steadily without flickering or making noise.
What happened to the flame as you covered the air holes?
The flame will start to weaken and eventually go out as you cover the air holes. This is because the flame needs oxygen to sustain combustion, and by covering the air holes, you are restricting the flow of air needed for the flame to burn.
How long can a person live without air?
A person can live minutes without air.
What is the nature is flame obtained when magnesium burn in air?
Very bright white flame - you can't look at it directly without damaging your eyes, and usually look at it through tinted glass.
