2. Introduction
Aim of the Experiment
To find out which will evaporate faster; Sugared water or plain water
My Hypothesis
I believe that plain water will evaporate faster than sugared water
3. Apparatus needed
2 Identical cups
with the same
surface area
A Beaker
A container
containing
sugar
The only variable that is changed is that 1 glass contains sugar while the other doesn’t
5. STEP 1
Pour some water into the
beaker. Preferably 200 ml. Pour
the same amount into both
glass. Both amt. of water in
each glass must be the same.
Preferably 200 ml each.
6. STEP 2
Mark each glass A and B. Then
decide which glass you want to
pour sugar into. In my case, I
put sugar into glass A.
7. STEP 3
Pour all the sugar in the
container into the glass that you
have chosen to put sugar into.
Then stir it well.
8. STEP 4
Then, mark the water level. This
part can be very tricky, but you
will have to do it right. If not,
your experiment can fail.
9. STEP 5
This will be the most longest
and final step. You will have to
leave the glass jar overnight or
longer for better results. In my
case, I’m leaving it for 24 hrs.
10. Conclusion and Explanation
Conclusion
Glass A has a slightly higher water level
than Glass B.
From this, we can conclude that plain
water can evaporate faster than
sugared water.
Explanation
Water is colourless and odorless, and
sugar water is made by dissolving sugar
into water. Sugar can absorb water
from the atmosphere, and this can stall
evaporation. Less energy is required to
evaporate water than sugar water
when the conditions are constant and
there is a significant amount of sugar in
the sugar water.
