Differential Scanning Calorimetry (DSC) was carried out to investigate the thermodynamic properties of CXB‚ different carriers‚ PMs and SD preparations. Their thermograms are represented in Figures (9-14). The thermogram of CXB in Figure (9) was characterized by single‚ sharp endothermic peak at 165±0.56°C which represents the melting point of CXB. Some researchers reported that CXB melting point ranging from 160.79–164.64°C (127)‚ and Paradkar A. et al. (2002) reported that sharp endotherm corresponding

SCH4U0 The Energy of Physical‚ Chemical‚ & Nuclear Processes The study of energy and energy transfer is known as thermodynamics. When this study of energy transfer is specific to energy involved in chemical reactions it is called thermochemistry. Studying Energy Changes The Law of Conservation of Energy states that the total energy of the universe is constant. (Energy can neither be created nor destroyed. [pic] Energy can be transferred from one substance to another‚ and it can also

Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy

HOT MECHANICAL WORKING 1. Ingost slow to solidify (Ingost can’t be used for engineering purpose) 2.Its structure is disorderly‚course and inhomogeneous chemistry and impurities. 3.Therefore ductility is poor and highly stressed. 4.The stresses are sufficient to repture if sudden temperature stress are induced. Reasons for hot working : 1. Reconstruction and refinement of crystalline structure. 2. Fragmented and arranged in a desired direction. 3. Section is reduced to a desired
