Does Alka Seltzer dissolve fastest in
cold, warm, or hot water?
!
My Science project
purpose is to find out if
Alka Seltzer dissolves
fastest in cold, warm, or
hot
water.
My
hypothesis is, if I drop
an Alka Seltzer into hot
water it will dissolve
faster because most
substances change
faster when affected by
heat.
!
To figure out the
answer I will fill three
glasses with cold, warm,
and hot water, label the
glasses according to
their temperature, drop
one Alka Seltzer into
each glass at the
same time, watch the
glasses to see which
one dissolves the
fastest, and record my
answers. ! T
h
e
materials I am using
for the procedure are
three clear glasses,
cold, warm, and hot
water, Alka Seltzer,
and labels. My
independent variable
is the different waters,
my dependent variable
is the Alka Seltzer,
and the controlled
variable is the
glasses.
!
During the
results the hot water
dissolved the fastest
and supported my
hypothesis. This
experiment shows
that if you have
heartburn and you
want it to go away
really fast you should
take the pill with hot
water.
