Hello everyone!
I am Yuhish Maharjan
I am 14 years old
I am from Nepal
I live in Lalitpur, Nepal
I am in grade 9
My school's name is West Wing secondary school
Today I am here to show you the experiment
named underwater candle experiment
In this experiment we can know how the
candle burns inside the water and we can
see the wick of the burning candle
Hello everyone!
Materials required for the experiment are
Lighter
Candle
Measuring tape
A glass of water
Small pin
Transparent bowl
First, stick the candle into the bowl
Do this by lighting the candle and
allowing the candle to drip into the bowl
Make sure that enough wax drip into the bowl
to make the candle stick
Once there is enough melted
candle wax in the bowl
stick the candle into it
Wait to dry for about five minutes
Next, pour water into the bowl
until just the top of the candle
You don't want the candle to be
fully submerged in the water at this point
After that, light the candle
My lighter is not working so I will be
using another candle to light this candle
Now, slowly watch as the candle burns
It will continue to burn even when the
wick is below water level
Sometimes, the candle dims and goes out
just before the candle dies
the water level rises almost
one 10th of the pitcher
No air bubbles have I seen
The water level stays up for
many few minutes more
We measure how far the candle
has burned down beneath
the surface of the water
Mine went down about 1,5 centimeters
That's all, this was my experiment
The conclusion of this experiment
goes like this
We can see that as the candle burns
A part of the wax surrounding the wick
does not melt
leaving a well of protection around the wick
This allows the candle to continue burning
even though the flame is already
lower than the water
Basically, the cool water surrounding
the candle is absorbing the heat
from the flame
This allows the wax to stay solid
instead of melting and dripping
on its sides like it normally does
and that is how the candle can
keep burning
That is all for my experiment!
Thank you!
