Introduction
In order to complete the snack energy lab, calorie and calorimetry will be use as a major technique. By burning pieces of food, the chemical energy stored in molecular bonds is released as heat and light. The heat can be measured in units called calories. A calorie is the amount of heat required to increase the temperature of one gram of water by one degree Celsius. This process leads to the foundation of calorimetry. A calorimeter, an object …show more content…
The more calories a food contains, the more heat is given off when burned. Foods high in calories will release large amounts of energy. One gram of a protein will release far fewer calories than one gram of fat. Similarly, plants have evolved processes that convert light energy into chemical bonds of complex molecules. The chemical bonds in carbohydrates, fats, and proteins, store energy until needed by the plant. The plant then release the energy by breaking the appropriate chemical bonds. In addition, animals also maintains its life processes by consuming complex molecules that store energy. The processed plants and animals we eat as foods contain varying amounts of proteins, carbohydrates, and fats. Because each of these types of foods contains varying amounts of energy, these foods will release varying amounts of energy when they are used by cells. Within our bodies, the energy is released slowly by a series of chemical …show more content…
From the data, we were able to conclude that calorimeters are used to determine the calories present in different foods. Additionally, after the pringle burned, the mass was reduced by 1.49g, while the temperature increased by 22°C as it took the heat that came from the burning of the pringle. From then, you can use datas from the data table to calculate the amount of calories burning per grams such as 1.48 Calories/gram for the first trial. Heat is the energy that is transferred between objects when there is difference in temperature. Objects obtain heat as a result of the small, rapid motion that all atoms experience such as vibrations, rotational motion, and electron spin. The temperature of an object is an indirect measurement of its heat. Particles in a hot object exhibit more rapid motion than particles in a colder object. When a hot and cold object are placed in contact with one another, the faster moving particles in the hot object will begin to bump into the slower moving particles in the colder object making them move faster. Eventually, the two objects will reach the same equilibrium temperature--the initially cold object will now be warmer, and the initially hot object will now be
