  • Molar Dehydration Experiment

    equation, one that describes the molar enthalpy of dehydration. Calorimetry is using a tool, the calorimeter, which insulates the system from the environment. This allows for the changes of temperature to be observed with minimal heat loss to the environment. Calorimetry allows for the heat of the solution to be calculated since the heat capacity of the calorimeter is known and the change in temperature is observed. The heat capacity is the ability for the container to retain the heat the is produced or absorbed without allowing for the outside environment to impact the reaction. This closed system allows for easy calculations where q_rxn+q_water+q_calorimeter=0. This is important to the lab that the total heat lost and gained must all equal zero. It would be hard to calculate how much heat was lost in the world by the experiment, so isolating the system to the calorimeter allows for the…

  • Bomb Calorimeters

    a baked lay and through our calorimeter heat energy was pushed out. Then we took it another step further by modifying our calorimeter to capture even more energy. The overall purpose was to capture as much energy as possible. “Energy is the ability to do work, or the ability to elicit change in matter.” (Castro) Energy can be defined in different ways as well. Kinetic energy is energy that results from movement. (Castro) An example would be water flowing through a hydro dam. (What is…)…

  • Calorimeter Experiment

    The designed calorimeter and experiment was roughly 9.55 times more efficient than the control experiment. The designed calorimeter was also 48.99% closer to the accepted value (value obtained by industrial calorimeter accepted in industry). This is a huge improvement for how inexpensive and easy the calorimeter was to design and build, showing how inefficient the original experiment was. The calorimeter was designed based on the fact that heat permeates out of the flame in all directions and…

  • Calorimeter Lab

    Introduction The purpose of this lab is to find the most efficient way to capture energy from a combusted chip using a calorimeter. We made a basic calorimeter by using a steel can. Through out our lab we made modifications to the calorimeter to increase the percent of energy captured by the water. Literature Review Kinetic energy is the energy of motion. The kinetic energy of an object is energy that is being used. Potential energy is stored energy that it is not in motion, but has…

  • Copper Calorimeter Experiment

    This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…

  • Bomb Calorimeter Experiment Essay

    ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

  • Calorimetry Lab

    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 information we know that fat…

  • Molar Heat Of Fusion Of Ice Lab Report

    Procedure: Before beginning each experiment, remove all clutter from the workstation and read the directions for the experiments thoroughly. Part 1: Warm slightly more than 300 mL of water to approximately 70 degrees Celsius. Measure out 150 mL of water into the coffee cup calorimeter. Take the temperature of this water in the coffee cup calorimeter once it has reached a steady temperature. Then, add an ice cube approximately the size of a large marshmallow. Stir the ice and water and measure…

  • Heat And Calorimetry Lab Report

    Uneven heat distribution would be caused by insufficient stirring or excessive stirring. If the solution in the calorimeter was not mixed enough it would cause areas or warmer and cooler solution. Also if the solution was mixed intensely it may add to an increase of kinetic energy in the solution increasing the heat recorded. The heat from the system may have transferred to our hands as we held the top of the calorimeter down. This would cool down the system decreasing the final temperature…
