PPT-Calorimetry

603 Honors 603 Calorimetry honors In this experiment you will determine the quantity of heat involved in two different chemical processes The heat given off or absorbed will be measured using an insulated calorimeter Be sure to record all measurements carefully as you will use the data to calculate the enthalpy change of each process. Outline. Types of water. Differential Scanning Calorimetry . Nuclear Magnetic Resonance Spectroscopy . Analytical determination of types of water. Summary. Purpose. Types of water are removed in different ways. Mr. . Dvorsky. SCH 4U1. A calorimeter is an object used for measuring the heat of a chemical reaction or physical change. . Can be as simple as a pair of cups and a thermometer, or as complex as a device attached to the Large Hadron Collider.. Quick Review of Concepts. We have been introduced to heat producing (. exothermic. ) reactions and heat using (. endothermic. ) reactions. Heat is a measure of the transfer of . energy. from a system to the surroundings and from the surroundings to a system. Fall, 2010 Indirect Calorimetry 1 Indirect Calorimetry Indirect Calorimetry CALORIMETRY The science that quantifies the heat release from metabolism is termed calorimetry . Figure 4.5 CALORIMETRY D Why do some things get hot more quickly than others?. Temperature. Temperature. . – proportional to the average kinetic energy of the molecules. Energy due to motion. (Related to how fast the molecules are moving). Ohio University (Athens, OH, USA). Uniplast Ltd Co. (Vladimir, . Russia. ). PHENIX Calorimetery Workshop. 12/14/2010 BNL. Main Idea. We have done some preliminary calculations/considerations for the basic parameters of a few more “conventional” options: . Differential Scanning Calorimetry APPLICATION Measurement of Tg of Polypropylene Using the Double-Furnace DSC DSC 8500 The DSC was calibrated for temperature and enthalpic responses using high purity Enthalpy. Enthalpy (H)is the total amount of energy contained within a substance. Included all forms of energy, kinetic, potential…. Very difficult to measure all forms of energy within a substance, therefore a change in enthalpies is measured whenever a change occurs.. On the front counter there is a perpetually thirsty bird. Do NOT touch him.. Write down all your . observations. of the motion. Do not try to explain why it’s happening—just look at WHAT is happening. . SiD. ?. Adam Para. ALCPG meeting, December 20, 2007.

(the pathway does not matter) with . the symbol . H. ..  . H . = E . P V. E . is the internal energy of the system, P is the pressure of the system, and V is the volume of the system.. A Calorimeter. A device used to measure the heat involved in a chemical reaction.. The reaction is run in the inner container and the change in the temperature change of the water is measured. The specific heat of the water is KNOWN and the mass of the substance is measured BEFORE the reaction.. Reaction Energies. In our earlier discussions of calorimetry, we used . physical. sources of heat (hot metal slug). It is also possible to use . chemical. sources of heat (like hot packs and cold packs)..
