Abstract
Which almond has more calories: salted or unsalted? To find this there was an experiment conducted using the materials listed below. The results find that the unsalted almonds have fewer calories than the salted ones. To determine this a calorimeter was use to find the amount of calories in each. In conclusion the hypothesis was tested, found, and proven through the steps below.
Introduction
In this experiment the numbers of calories are being found in salted and unsalted peanuts. This will be done by using a calorimeter. The temperature will be taken from the calorimeter and converted into the calories that were burned in the sample.
Purpose/ Hypothesis
The reason for this experiment was to find out the difference in calories between salted almonds and unsalted almonds. The food was burnt and using a calorimeter the temperature was found and was converted into calories.
Materials and Methods * * Compass/Scissors * Pop Can * Matches * 3 Paperclips * Baby Food Jar Lid * Support Stand * Ruler * Ring clamp * 3 Salted Almonds * 3 Roasted Almonds * Distilled Water * 50 mL Graduated Cylinder * Thermometer * Scale
A baby jar and a can of soda were both emptied and thoroughly cleaned. Then the jar was disposed of and the lid was kept. A ruler was then used to measure two centimeters down from the top of the pop can and holes were made using the compass/scissors every 90 degrees around the can. Then two of the paperclips were straightened and inserted through the holes until they came out the other side. Then the other paperclip was bent to make a stand to hold one almond. Then the paperclip was hot glued to the baby food lid to make a stand.
After that the 50mL graduated cylinder was filled with 50mL of distilled water. Then the empty can with the paperclips was weighed and recorded. Then all the water was added to the pop can. Then the almond were placed on the baby food lid holder and weighed and recorded. Then the ring clip was attached to the support stand. Then the pop can was placed on the ring clip and adjusted to where there were two inches of space between the pop can and the almond.
Once that has been done then light a match and ignite the almond. Then just let the almond burn. Once it has burnt all the way down take the temperature of the water in degrees Celsius. Record the temperature, and weigh the almond sample and the pop can. Then pour out the water, and dispose of then almond. Then do the same burning and weighing process five more times
