Lab 4.2 Heating and Cooling Curves Of Lauric Acid.

Paragraph #1

Based on Jake Eggleston and Nate Gillian's data the melting point of Lauric acid is 46 degree from the above graph and the Freezing point of Lauric acid from the second graph is  also 46 degree the two values are the same. To determine the Melting point of Lauric acid on the Heating curve of Lauric acid i looked at the lowest x value on the graph and they were constant so i figure out that it was the melting point and i kind of did the same thing on the second graph to figure out the freezing point on the cooling curve of Lauric acid.

Paragraph #2

Kinetic energy is the energy that an object has because of his motion . Kinetic energy increases during the heating curve when it's at the solid phase and liquid phase and also gas, Kinetic energy decreases in the cooling curves in the steam cools, also as the solid cools and at the condensation point  .The Potential Energy is the energy that is stored in a material, the amount of which is determined by the structure of the particles and/or their positions relative to each other. Potential energy increases in the heating curve at the melting, vaporization state and the potential enery decreases in the cooling curves as the gas system condenses to the lquid phase and at the freezing point liquid water loses potential energy as bonds form to hold molecules in fixed positions in the solid state.

Enrichment :

The actual melting point of lauric acid is 44'c. We found that the melting point of Lauric Acid was 46 degrees. The percent error was 4.45%. This could have been because when we were doing our experiment we didnt stir the Lauric enough. Latric Acid is often used for soaps and shampoos. It's in soaps and shampoos because it helps dissolve fats.It helps shampoos remove grease from your hair to make it look good.
