Introduction The first law of thermodynamics states that the energy of the universe is constant. Heat is transferred when the atoms of one material vibrate and collide with the atoms of another material‚ thus transferring energy. For this reason‚ heats always travel from hot to cold objects and two objects will reach an equilibrium temperature. Materials and Methods 1. Oven 7. Test Tube 2. Pasco Temperature Probe 8.

Mustard Gas During World War I LOST was the original name for mustard gas‚ it was named after Lommel and Steinkopf. They were the first people who proposed this gas to the military to use as a weapon in 1916. Although mustard gas could possibly been developed as early as 1822 by a French chemist‚ Cesar-Mansuete Desperetez. Thirty-two years later Alfred Riche repeated this reaction of the sulfur dichloride and ethylene‚ but both Riche and Desperetez did not note any harsh properties. In 1860‚

Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before

is * Sulfur mustard is a type of chemical warfare agent. These kinds of agents are called vesicants or blistering agents‚ because they cause blistering of the skin and mucous membranes on contact. * Sulfur mustard is also known as “mustard gas or mustard agent‚” or by the military designations H‚ HD‚ and HT. * Sulfur mustard sometimes smells like garlic‚ onions‚ or mustard and sometimes has no odor. It can be a vapor (the gaseous form of a liquid)‚ an oily-textured liquid‚ or a solid

Abstract: The topic of this research involved the occurrence of genetic transformation in bacteria (E. Coli). More specifically‚ a previously prepared pGLO plasmid--which consisted of the gene to be cloned--was used to transform non-pathogenic bacteria. The pGLO plasmid contained a gene for the Green Fluorescent Protein (GFP) from a bioluminescent jellyfish and a gene for resistance to ampicillin‚ an antibiotic. Essentially‚ we wanted to determine the conditions of the bacteria that would glow.

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were
