Lab 4.2

In blog 4.2, we observed the changes in the energy of the lauric acid as it changes from one phase to another when adding or decreasing kinetic energy. 

Step 1) Obtain 5 grams of the lauric acid and put it into a single test tube.

Step 2) You then begin heating the beaker full of this substance and record the temperature every 25 seconds to get the most efficient results.

Step 3) Then, you put it in a beaker full of ice and recorded that data every few seconds to get the the top of the line results 

Step 4) After all this is finished, we graphed the data and begin to observe the curves of those two experiments.
The melting point and freezing point on both graphs are relatively the same; but they were off by not very much. These two values should be the same because they both become a liquid at the end of the experiment.

Kinetic energy is the energy in a substance due to it's particle movements. In the heating curves graph it is increasing and in my cooling curves graph it is decreasing. Potential energy is the energy that a substance has due to the position it is in. My potential energy in my heating graph is increasing as it is decreasing in my cooling graph. This makes sense because when something heats up, the kinetic energy and potential energy increase because the particles are obtaining more energy.

Enrichment:
Lauric acids actual melting point is 44 degrees celsius. Mine was different because i must have miscalculated.

Lauric Acid is a  fatty acid, CH₃(CH₂)₁₀COOH, obtained chiefly from coconut and laurel oils and used in making soaps, cosmetics, esters, and lauryl alcohol. It is also used in many oils, humans milk, cows milk, and goats milk
