Salt vs No Salt
!
The purpose of my
experiment was to find out if
salt affects the amount of
time it takes for water to boil.
My hypothesis was that the
water with no salt would boil
the fastest, because salt
raises the boiling point.
!
The materials needed
for my experiment include: a
pot, water, three cups of salt,
a stove top, and a timer.
!
For my procedure I
measured out one quart of
water for each pot and put
the stove on the hottest
temperature the stove top
could go. For pot A, I added
two cups of salt to the
water, for pot B, I added
one cup of salt to the
water, and pot C, was just
the plain water. Then I
timed how long it took for
them to come to a rolling
boil.
!
The independent
variable was the amount
of salt I put in the water.
The dependent variable is
the amount of time it takes
for the water to boil, which
was affected by the
amount of salt I put in the
pot. The controlled
variable is the amount of
water I put in each pot, the
temperature, and the pot I
used.
!
The result of my
experiment was that the
water with no salt boiled
the fastest with the time of
7 minutes and 49 seconds.
In conclusion my data
supported my hypothesis.
My hypothesis was that the
water with no salt would
boil the fastest because
salt raises the boiling point.
I can relate this to real life
by thinking, if I ever need
something to cook faster,
to not add salt.
