    The Calorimeters Calorimeters are a device that can measure the heat that comes from burning an item. Simple Calorimeter A simple calorimeter is used to detect the enthalpy change when a fuel is burned. The fuel is burnt to heat a specific mass of water and then measure its rise in temperature. The word calorimeter comes from the Latin phrase calor which means heat. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber

    ________________________________________________________ introduction Chemical reactions absorb or release heat. One way to measure this is by using a homemade calorimeter. The calorimeter used in this experiment is made up of a Styrofoam ball with a hole that can fit a test tube. The heat capacity of the styro-ball calorimeter is measured using a neutralization reaction of know enthalpy change. This heat capacity is then used to calculate the amount of heat absorbed or released by a chemical

    experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The bomb is submerged in 850g of water and the initial temperature of calorimeter state temperature of calorimeter water before burning the fuel‚ Ti is

    procedures require the use of a calorimeter‚ which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this is not completely true‚ they are treated as isolated systems. A simple coffee-cup calorimeter can be constructed using two Styrofoam cups nested inside each other. The Styrofoam prevents heat loss to the surroundings‚ which makes it an ideal calorimeter.

    • 4 Pages

    Discussions and Scientific Explanations The first goal of this project was to first construct a calorimeter. The second goal was to measure the heat capacity of the constructed calorimeter. The third and fourth goal was to determine what reactions were to be investigated and what variations of the reactions would be studied. The two requirements that were kept in mind while creating the calorimeter were that it should be a good insulator‚ meaning that it does not allow for the transfer of heat

    Experiment B2‚ Heats of Combustion – The Bomb Calorimeter. Objectives: To calibrate a bomb calorimeter by the combustion of benzoic acid. Then to use the calibrated calorimeter to measure the heat of combustion of naphthalene and calculate the heat of formation of naphthalene. Theory: q = C.ΔTBA C = q / ΔTBA Moles = mass / Mr ΔŪ = ΔU / moles ΔHoc‚298 = ΔŪoc‚298 + PDV = ΔŪoc‚298 + RTΔn C10H8 (s) + 12O2 (g) 10CO2 (g) + 4H2O (l) ΔHoc‚298 = - 1

    The purpose of this experiment is to find what design of calorimeter captured the most energy from a combusted chip. To find this‚ we tested each design‚ and calculated the amount of energy it captured from a baked potato chip. The two basic forms of energy are kinetic energy and potential energy. Kinetic energy is the energy of motion. A ball has kinetic energy when it flies through the air. The ball has the ability to do work in that it can act upon other objects with when it collides. Potential
