Calorimeter

A calorimeter is a device used to measure heat of reaction. It can be sophisticated and expensive or simple and cheap. Bomb calorimeters are a more advanced way to more efficiently measure the heat released by combustion reactions. A bomb calorimeter is a sealed vessel that contains a smaller container called a "bomb." The bomb is a container designed to withstand high pressure…

Company, a company that manufacture and sale laboratory instruments include calorimeter. Calorimeter is a machine that used to determine the potential calorie of a test object. With the breakthrough of newly developed technology, Parr Instrument Company can now reduce the size of the calorimeter from a photocopy machine to the size of a laptop. Therefore, I will introduce a new product GV, a Personal Calorimeter. Personal Calorimeter is a machine that can quickly calculate the amount of calorie…

be able to lower the enthalpy when is mixed with water. This will cause an exothermic reaction and release heat. This experiment had three tests performed within it, The freezing point depression, the enthalpy of dissolution, and finding the calorimeter constant. Even though, the results in this lab had a high present of error it was found that magnesium chloride is an effective deicer because it is relatively cheap and is safer for the environment than other deicers. Introduction…

the metal to the temperature of the boiling water (100.0°C). 4. While the metal is heating, nest one Styrofoam cup inside the other. This will be your calorimeter. Since Styrofoam is a good insulator, 2 Styrofoam cups make an excellent calorimeter. 5. Measure the mass of this calorimeter with your scale. After you do this, fill the calorimeter about three-quarters…

calculate the enthalpy of a reaction, a calorimeter is used to measure the change in heat energy from mixing different substances. The change of temperature is found by comparing the change in temperature of the system to the temperature of the surroundings. For a calorimeter, a Styrofoam cup place in a beaker is used. The Styrofoam of the cup minimizes heat loss and the beaker keeps the cup in a stable position. Hot and cold water were mixed in the calorimeter to calibrate it and determine its…

coffee cup calorimeter could be recorded. The temperature probe was plugged in and the “Time Based” data collection settings were adjusted so that there was a 15 s/sample interval so that there was an 180 second cycle for part B. The calorimeter was then set up so that the first reaction of hydrochloric acid and sodium hydroxide could take place. Two Styrofoam cups were…

purpose of this lab is to test for the most efficient way to transfer heat energy from the chip to the water beaker. The heat transfer was coming from burning a baked lay and through our calorimeter heat energy was pushed out. Our experiment was taken one step further to continue to modify and build a better calorimeter. Overall the purpose was to find the best way for energy to be captured. Literature Review Anything around us is generally matter. Everything we touch, the buildings we…

In our experiment, to look deeper into exothermic reactions, we first had to create our own calorimeter. We did this using 3 separate 8 ounce Styrofoam cups, one for each compound. We then used cardboard to create a lid for each cup and taped it to the sides so the seal would be as tight as we could make it. We also needed a 150mL beaker to measure out the 50 mL of distilled water that we used in each trial to dissolve each compound in. To weigh out each compound we also needed an electronic…

The objective of the lab was to find the calorie content of Cheetos and marshmallows. To do this we needed to use a calorimeter. The hypothesis was that Cheetos would have more calories because they have more fat in them. The Cheetos and marshmallows were lit and put in an oatmeal can calorimeter. The temputure change in the water leads to finding the calories in food. Cheetos had about 3x the amount of calories at 1.66 calories per gram compared to marshmallows 0.57 calories per gram. With this…

The goal of this lab was to determine the heat of fusion of ice (or water). According to Chem.Libretexts.org, Heat of fusion is where solids are heated to a specific heat capacity (The number of heat units needed to raise the temperature by 1 degrees) in order to break the bonds that are keeping them attached, which is called the attractive force. This lab also dealt with the concept of the direction in which a temperature follow. According to chemistryexplained.com, temperature is the measure…
