Dissolving Candy
BY: ALEXANDER ENCINAS
Problem: Will the temperature of liquid
decrease or increase the time it takes
to dissolve a piece of candy.
Research:

Higher temperature leaves less space for particles to move and has higher
kinetic energy.

Lower temperature leaves less space to move and lower kinetic energy.

In lower temperature the viscosity is higher which leaves less room.

In higher temperature water the viscosity is lower which leaves more room.
Hypothesis:

If I put a piece of candy in three different temperature of water.

Then the warmer container of liquid will dissolve the candy faster

Because the kinetic energy is higher.
Procedure:

Materials: Three cups of water, candy, and clock.

Steps:

1. First, I get three cups of water and have different temperatures In
each cup.

2. Second, I place a piece of candy in each cup with different
temperatures.

3. Third, leave each cup of water with candy inside at different time
lengths and check on each cup.
Observations:

In the hot water cup the candy formed bubbles on the edge and the
color was coming of the candy. The candy was slowly dissolving and
moved around the container.

In the room temperature water cup the candy as well formed bubbles
around the edge and the color was not fading away, but it was slowly
dissolving.

In the cold water cup the candy also had bubbles on the edge and no
change after a couples days. After the first week the candy finally was
almost done dissolving.

Constants: pieces of candy.

Control: Higher temperature water and lower temperature water dissolve
rate.

Independent variable: Dissolving of candy.

Dependent variable: Time it takes to dissolve the piece of candy in the
three different temperatures.
