PPT-Calorimetry

Physics 12 Objectives Define specific heat capacity Solve problems involving specific heat capacities Explain the difference between solid liquid and gaseous phases Explain in terms of molecular behavior why temperature does not change during a phase change. Measured values show the thermophysical properties of the examined system or sample There are two bas ic types of calorimeters isothermal and adiabatic Constant temperature is sustained in t he isothermal calorimeter t means that the calorimeter is Differential Scanning Calorimetry APPLICATION Thermal Analysis of Lipsticks Utilizing DSC DSC 4000 For a complete listing of our global offices, visit www.perkinelmer.com/ContactUsCopyright 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. It operates under the law of conservation of energy (what is that?). Heat loss = Heat gained. A device used to measure the absorption or release of this heat is called . Calorimeter. Watch a video lecture for an example.. 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. The history of bomb calorimetry reaches back into the late 1800 Fall, 2010 Indirect Calorimetry 1 Indirect Calorimetry Indirect Calorimetry CALORIMETRY The science that quantifies the heat release from metabolism is termed calorimetry .

We have done some preliminary calculations/considerations for the basic parameters of a few more “conventional” options: . 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.. calorimetry Enthalpy changes in reactions Calorimetry and heat measurement Hess’s Law Heats of formation Learning objectives • Describe the standard state for thermodynamic functions &# Heat Capacity. Specific Heat Capacity (c): . the quantity of thermal energy required to raise the temperature of 1 g of a substance by 1°C.. Units are in J/g∙°C. Heat Capacity. Specific . heat capacity values can be looked up in tables. SiD. ?. Adam Para. ALCPG meeting, December 20, 2007. Other Possible Titles. Homogeneous Dual Readout Calorimeter.

We relate energy and temperature by discussing a substance’s heat capacity.. Heat Capacity = heat required to raise temp. of an object by 1. o. C. more heat is required to raise the temp. of a large sample of a substance by 1.
